Ideally the carb bodies should be cold and the intake manifold hot. So if you can tie the shield to the manifold, that would be best. Some use the fuel bowl clean-out screws at the bottom of the carb to connect a heat shield but this brings heat into the fuel. If you could make some brackets that ran from the top of the manifold to each end of a long single heat shield under the carbs, that would be convenient. Making or finding bolting points on the top of the manifold would make removing the shield a lot easier. Typically the current shield are bolted in very inconvenient locations. This is the idea I am proposing but the brackets would connect to the manifold rather than the carb: This design puts heat in the fuel:

50 years ago this month! May 1969 - total 2 cars - one domestic, one export: 1 = S30-00001 (Factory prototype 1) 2 = HLS30-00001 (Factory prototype 2) Thanks to @kats below are pictures of very early 240z HLS30-?????

Nice car!

Nope, the point I am making is ALL HUMANS on the planet can trace their ancestors to Africa!!! Very profound unification.

Rear main seal or side seals are leaking?

Here are calipers in FSM that was photographed probably summer of 1969: Sumitomo on the casting.

I'm in love!

Nope, we are all African according to scientific research and evidence. Most North Americans arrived from Africa via Europe after waiting in Europe for transoceanic ships to be invented. Others arrived by walking the long route from Africa to Middle East, to Asia, to Alaska. They arrived earlier but all paths are from Africa. The crazy aboriginal "rights" in Canada would not agree with the above. They would claim that they were here first and own all the land.... so if we apply this to the Moon, the USA owns it as Armstrong was there first.... but his ancestors came from Africa. FYI: I was riding on the Mayflower When I thought I spied some land I yelled for Captain Arab I have yuh understand Who came running to the deck Said, “Boys, forget the whale Look on over yonder Cut the engines Change the sail Haul on the bowline” We sang that melody Like all tough sailors do When they are far away at sea “I think I’ll call it America” I said as we hit land I took a deep breath I fell down, I could not stand Captain Arab he started Writing up some deeds He said, “Let’s set up a fort And start buying the place with beads” Just then this cop comes down the street Crazy as a loon He throw us all in jail For carryin’ harpoons Ah me I busted out Don’t even ask me how I went to get some help I walked by a Guernsey cow Who directed me down To the Bowery slums Where people carried signs around Saying, “Ban the bums” I jumped right into line Sayin’, “I hope that I’m not late” When I realized I hadn’t eaten For five days straight I went into a restaurant Lookin’ for the cook I told them I was the editor Of a famous etiquette book The waitress he was handsome He wore a powder blue cape I ordered some suzette, I said “Could you please make that crepe” Just then the whole kitchen exploded From boilin’ fat Food was flying everywhere And I left without my hat Now, I didn’t mean to be nosy But I went into a bank To get some bail for Arab And all the boys back in the tank They asked me for some collateral And I pulled down my pants They threw me in the alley When up comes this girl from France Who invited me to her house I went, but she had a friend Who knocked me out And robbed my boots And I was on the street again Well, I rapped upon a house With the U.S. flag upon display I said, “Could you help me out I got some friends down the way” The man says, “Get out of here I’ll tear you limb from limb” I said, “You know they refused Jesus, too” He said, “You’re not Him Get out of here before I break your bones I ain’t your pop” I decided to have him arrested And I went looking for a cop I ran right outside And I hopped inside a cab I went out the other door This Englishman said, “Fab” As he saw me leap a hot dog stand And a chariot that stood Parked across from a building Advertising brotherhood I ran right through the front door Like a hobo sailor does But it was just a funeral parlor And the man asked me who I was I repeated that my friends Were all in jail, with a sigh He gave me his card He said, “Call me if they die” I shook his hand and said goodbye Ran out to the street When a bowling ball came down the road And knocked me off my feet A pay phone was ringing It just about blew my mind When I picked it up and said hello This foot came through the line Well, by this time I was fed up At tryin’ to make a stab At bringin’ back any help For my friends and Captain Arab I decided to flip a coin Like either heads or tails Would let me know if I should go Back to ship or back to jail So I hocked my sailor suit And I got a coin to flip It came up tails It rhymed with sails So I made it back to the ship Well, I got back and took The parkin’ ticket off the mast I was ripping it to shreds When this coastguard boat went past They asked me my name And I said, “Captain Kidd” They believed me but They wanted to know What exactly that I did I said for the Pope of Eruke I was employed They let me go right away They were very paranoid Well, the last I heard of Arab He was stuck on a whale That was married to the deputy Sheriff of the jail But the funniest thing was When I was leavin’ the bay I saw three ships a-sailin’ They were all heading my way I asked the captain what his name was And how come he didn’t drive a truck He said his name was Columbus I just said, “Good luck”

Land of the free? Seems like California is becoming Europe!

This style gets good reviews: https://www.harborfreight.com/electric-body-saw-65766.html

I'm more of a Herman fan but it is similar to Far Side..... Binky the bunny is best

JB Weld?

Unscrew it, seal the threads and screw it back in.... see if that does the trick. If not then it should be changed out.

Vibrating table, blue rocks, and a friend's 240z tank.

Nice car! You are lucky to get help from Hardway! He is a great guy and very knowledgeable Z head.

My friend's Z. He did it. I think he preferred the knob on the outside.

Miatas handle like a dream but the torque of the Z is addictive. btw you may want to re-fit the front grill. It seems to be off a little.

All 1970 cars I have seen just have the round knob for back tilt. There was no flip forward lever. Here is one with the knob on the outside.

Propane heat on the bolt and head area...along with some liquid wrench to cool will do the trick

I'll simplify my suggestion: 1. The ball wants to fall vertically in Y axis due to the force of gravity. 2. The cart can only push/pull in X axis (i.e. it can not push ball upward in Y direction). This limits all forces to right the pendulum in the X axis.... so the force of the falling ball has to be translated to X axis. 3. The ball-on-a-stick is a classic torque model where the rotational force at the fulcrum can be broken into an X and a Y component proportional to the angle. (Typically θ is drawn between the arm and X axis and cos θ would be used to obtain X component of force but in this case sin θ is needed) Once the relationship with the torque's X component is expressed, the rest is just translating this to the pulley and strings then translating to voltage.

I think it is just a torque problem. The basic element is force in the +X direction from the car on the ball transmitted along the shaft has to counter the -X direction force of mg from the ball falling.... which I believe is proportionate to sin θ. When θ is negative and the ball falls in -x everything is reversed. Equation of motion is F=ma for the cart where F is equal to the X component of F=mg Sin θ from the falling ball. Seems like a Segway. btw I'm not an engineer ?

Blue came with similar... and high-water off-road suspension lol @Carl Beck :

These seem to be similar to Alan's swatches:
