I have a 94 ram 1500 5.9L auto and I'm removing a spacer but I need to get stock bolts to remount the throttle body. The issue is no auto parts store carries them. Mine are too long with the spacer out. And I don't know how long I need with stock. And I can't pull a bolt and drive to the parts store to match it up to something. Does anyone know where I can order them or the exact size, thread, and pitch? It is recommended that they are replaced everytime they are removed do they have to offer them somewhere.

 

Replaced when removed? I reused mine. Grab some from a junkyard.

 

You could pull one out, measure the length and minus the spacer height.
I assume 5.2 has the same bolt, so here's the specs: length is 2.28" (58mm) and thread is UNC 5/16-18. There's a washer attached to a bolt, but if you can't find same kind of bolt, you can go with separate washer.

 

Do they really need replaced? I'm having a hard time finding the new bolts. I got 4 good ones from the junkyard. Why do they have to be replaced?

 

I've reused mine. If the junkyard ones are still solid than use them
