When you do your 3D prints make sure to use filament that will withstand the temperatures inside a hot car and also not react with the UV from the sun. Roo

The Trico 44-200 is the same blade but 20" instead of 18". I just cut them down. Available on EBay for $15 shipped. https://www.ebay.com/itm/266517031540 Roo

Have sent you a PM to buy it. Roo

Now I know what to look for I'll keep an eye out on EBay and CraigsList. Thanks for everyone's help. Roo

I believe you are correct, that's the one I need if anyone has a spare they would like to sell. Roo

Thanks @Terrapin Z I'll take a picture of the ones I have on 8802 and 10991 and post them. I'm looking for one to go on 3801 (May 1970). It should be like this one on 4684 (May 1970).

I believe it may have been used until mid 1972 when they changed to a version with a shorter round section.

Looking for a throttle/accelerator bell crank for a 1970 240Z. Will be refurbished so doesn't have to be perfect. Roo

The washer with the holes in it came off the outer steering tie rod. It goes over the threaded bolt to restrict the amount of grease that goes into the dust cap. The Stubby bolt fits in place of the grease nipple once the fitting has been lubricated.

Down under we called that outback engineering, love that you got it to run!

Anyone know how to decipher the date codes on a 240Z caliper. Have seen lots of numbers on both sides but not sure what they mean.

Is it really necessary to trash other people's car's on here. It's one thing to question if things are done correctly or not but outright criticism is really bad manners.

All sorted, packed and in the mail to @fusion Helps clear out my garage!

I got a set in a lot of bits off ebay a few months back. You are welcome to have them as I have no use of them. If you cover the postage they are yours, would rather see them get used than sit in a pile in the back of the garage. Just PM me your mailing details. Roo

As I return my May 1970 240Z back to original specification I'm in need of a flat mustache bar to fit a R180 diff. The car came to me with a R200 diff, so that is being replaced with a R180. I have 2 curved later mustache bars if anyone is interested in a swap. Roo

@Terrapin Z does it show what Lot S83 the Vintage 240Z went for?

Thanks @hiyabrad $120k seems a fair price for it considering the missing parts. Did it have the original engine?

I think most people are missing the point, auctions are about getting the highest amount possible for the item on offer. They don't care whether they educate the public or not, it's all about the sale. I've seen dogs get sold for ridiculous amounts at auction due to the excitement and euphoria in the room. If they can find a buyer for what they are expecting it's worth then good luck to them., if not it will pop up elsewhere for sale. The armchair experts love to complain and point out why it shouldn't achieve reserve, at the end of the day no one really listens or even hears them and the car sells. The next owner may chose to have it restored correctly but that doesn't matter at the auction. The white 1969 240Z from the same collection https://www.mecum.com/lots/1088318/1969-datsun-240z/ also has a very high estimate, be interesting to see if it sells.

@Carl Beck aero power is the amount of horsepower required to push the car through the air, rolling power is the amount of horsepower to push the object but taking into account the weight and resistance to movement.

Makes loads of sense @kats Drag on a car body increases with the square of speed. In other words the energy required per unit of distance to overcome aerodynamic drag increases in proportion to the vehicles speed. The aero power required for each car to achieve 140kph is G-nose 38.63bhp and Basic 47.35. Basic nose standard 240Z requires 22% more power for same speed. For 160kph G-nose 58.674bhp and Basic 71.98. Basic nose standard 240Z requires 22% more power for same speed. From those numbers you can understand why the G-nose can out-accelerate the Basic nose on the standard 240Z.

@kats glad you are excited. The computations are based on the figures you supplied from the Datsun Japanese aero study and the windtunnel tests done in the USA. The formula used to calculate it is based on published figures, Datsun quoted 150ps for the power, I used their figure. All the data is readily available, no hocus pocus. If you can provide the aero figures for the European 240Z I would be happy to calculate the result. The aero horsepower required to push the standard 240Z through the air to achieve 125 mph would be around 140bhp, this doesn't take into account parasitic drag losses due to tire friction etc.

@kats The Racer Brown car with the G nose/tail spoiler and using a CD of 0.381 would have had a top speed of 160.81mph. The standard 240Z with the same horsepower as the Race Brown car and no aero (CD 0.50) would have a top speed of 146.88mph. The G nose with tail spoiler gives a 10% speed improvement. Standard 240Z with standard 150bhp engine and no aero would have a top speed of 124.89mph Standard 240Z with BRE front and rear spoilers would a top speed of 129mph.

@kats it's late here but I'll run the aero figures tomorrow and give you an answer. The Racer Brown 240Z was running around 240bhp so it should be easy to work out. What horsepower do the blue and yellow car have?

Actually it does the opposite, the opening to the rear of the hood brings air into the engine bay rather than venting it. It's a common place to draw air into the interior of the car for ventilation, hence the vents on the panel there. It's also used to feed air into the carbs on many race cars. Here's a good example.
