I bought my car, no driveshaft and it was an automatic. Now i have a CA18 swap, but no tranny crossmember bolts and no driveshaft bolts. Can anybody help me out with what the measurements are for these?

I need the measurements for the 4 Bolts for the driveshaft to the diff.
and ALL the bolt measurements that mount the Crossmember to the car.

Ive searched and check the FSM but found nothing. Thanks Guys.

The transmission crossmember to chassis bolts are the same pitch as the front seat bolts, I think they're M10x1.25 but you can pull one and match it up that way.
Driveshaft to diff are M8x1.25.

You are correct, sir. Just confirmed with the bolts I had.

nope
try getting SS ones so they dont rust

also grade 8 and above above

that means iso 10.9 and 12.9 only

no 8.8's
ZakS13

so only above 8 grade bolts? so pretty much i'd walk in there, ask the "Home Depot" people for grade 10 bolts of M10x1.25 and M8x1.25?

But there's plenty of Sentras, Altimas, Maximas, and trucks. You think the 240SX uses specific bolts made just for that chassis and no other car? Any Nissan, Toyota, Mazda, Honda, and nearly any other Japanese built car will have the same type bolts.
