Does anyone know of the procedure for removing that tin can cover in order to get the rag joint out? Trying to do this on my70 C-body, but I can't find the head of the bolts on the other end from where the nut is. It seems to be covered over by the tin box somehow?
Nothing in my 70 shop manual on it.

 

There are 3 tiny ass screws that are usually rusted pretty badly
Vide grips are usually required

 

The tin can cover is held on with 3 phillips head screws. They can be a pain in the arse but access to the rag joint is nearly impossible without removing it.

The 4 bolts that run through the rag joint are big allen head bolts that are countersunk into metal "triangles" in the rag joint, two in either direction.. The nuts will have nylock inserts and cotter pins.
