i just swapped my engine but do not have some parts. i need to know what size studs and bolts i need for the headers to mount to the motor exhaust manifold. i know what size socket i need, i need to know the actual thread size of the bolts and studs. some1 help?

 

Luckily my Helms is handy.

8 x 1.25mm thread.

 

is that the same size for the three bolts that connect to the down pipe? I have a big exhaust leak and wondering what size socket that will fit..my guess would be 14mm? two are studs connected by nuts but one looks like it should be connected by a bolt..any help is appreciated..

 

It's probably the same, and they should be 12mm nuts (6mm thread is typically 10mm bolt head).

Also, the stock manifold and A-pipe are held together by 3 studs w/ nuts on them, no bolts. Sometimes the nut likes to fuse itself to the stud, and the whole nut/stud combo comes out of the manifold, and it's a huge PITA. Even when I try to shoot them off quickly with my impact, the stud still comes out of the manifold.

 

ok cool..thanks alot for the help..
