Hey guys just realized i'm missing a bolt and was wondering if anyone could tell me the correct bolt to buy/same bolt someplace else on truck to take in...its one of the bolts that don't thread completely through, threads in on the engine side (not tranny side) Any help would be appreciated as this chattering knock is getting on my nerves..

1990 Laredo 4L 5spd

 

That looks like the dust cover to bell housing. 3/4- one inch long will be fine. May well be 5/16-coarse...pretty common. I think there are one or two others if you want to pull one to match. Better yet, pull that plate and check the torque on the T-converter to flex plate bolts. They are known to loosen and cause trouble. (in an auto) Oh manual...5/16 ths. I'd bet.

 

thanks for your reply..got it 5/16 coarse thread, 3/4 in long. ill try it out

 

I Keep forgetting I want to find my cover and put it back....I didn't mind having it off till I realised something might get up to the CPS in there. Good luck. 1/4 is pretty small and 3/8 is pretty big....I think it's 5/16.
