I have a Fiberglass (recently just sold the urethane one before installing it) Type 1 airdam for my 280z. Of course, it did not come with any hardware. Just looking at it, it seems like I'll need 6 bolts, 6 nuts, and 12 washers. What size bolts did you guys use for hardware? Anyone remember? And I'm assuming I should use stainless?

Hello guys! I'm new to this forum and recently new to the datsun world I purchased a 1981 280zx datsun that has been sitting outside a barn for about 4-6 years and since it still had the engine I decided to see if I can get it running before I even consider swapping the same l28e or if I get lucky the l28et. The first things I did was: change the oil, replace the fuel filter flush tank and replace gasoline (regular) replaced battery with terminals flush and replace coolant, spark plug wires (all in correct firing order) change ngk spark plugs (gaped .42 and added oil in each cylinder for lubrication) I cranked it with no luck, I heard the oil pump running loudly but decided to use starter fluid. Once started fluid was sprayed and the engine was cranked and the engine started and was running on starter fluid so my next steps were: clean injectors clean fuel rail replace o rings and insulation I cranked it again without starter fluid and it only cranked but didnt start. So I did a compression test and numbers were 140, 145, 145, 140,145, 155 so compression is pretty good being that 180psi is like new. I removed the fuel return line and cranked the engine and gasoline came rushing out, I tested the spark and its a blue with white tint, engine sounds like it wants to start so timing is good (?), exhaust smells like gasoline and has pulses, and it still doesnt want to start. Each time i remove the spark plugs after attempting to start it, i can see a little wetness on the tip and it smells like gas. It started once with starter fluid but now it just doesnt want to even with it. What do you guys think can be the problem? thank you!

Hey guys, I recently had an AC system installed in my 240z, it's a second generation 280z AC unit and I had an issue with it since I kept feeling hot air coming into the car at high speeds. So after a bit of checking I noticed two leaks from the firewall which i sealed off and one more larger hole on the passenger side, under the dash that brings in air from outside (picture attached). I ended up sealing that large hole as well with insulation foam and it solved my hot air coming in issue BUT, now I have another issue. I can now smell exhaust fumes in my car. My theory is when I sealed that large hole the air pressure in the car changed and it is now sucking or letting air in. Does that make sense?
