Exhaust manifold bolt locks
 

I am finishing up my engine rebuild and getting ready to reinstall the exhaust manifolds. When I took them off, the lock thingies broke in pieces from corrosion. Does anyone know where I can get new ones or ones in good condition. I want to keep the truck as original looking as possible so I would like to have the original looking locks.

hi Dan,great progress.i think you'll also find,if they didn't rust away,a small diameter but thick flat washer under the heads of the exhaust manifold bolts.i probably have some here i can mail to you if yours are gone or in bad shape.

I will let you know in my next update to you.

Thanks Greg!
