Due to not torquing a rocker arm bolt I have broke the aluminum piece that holds rocker arm down! And bent a push rod. I can get a new rod but can't find the aluminum piece and new bolt. I've read that I can use newer dryly from 7.3 but can I just replace what is needed or do I have to do all?

 

Aluminum piece?

 

That's easy to do. You have to replace the pair of rockers with the 7.3L style and replace everything as an assembly. You aren't going to find the old style rocker pivots with the bridge any longer. They aren't expensive and are readily available.

 

I have a rocker arm set new in the box. send me a p.m.
