Does your engine have shaft mounted rockers or are they stud mounted?

Shaft mounted rockers = LA
Stud mounted rockers = Magnum
 
no idk why... in total its broken 5 rocker arms.. over the span of 6yrs tho///

whats shaft mounted and whats does stud mounted look like
 
oh ok im told its LA crate.. but i dont have a spec list or anything :/
 
That's them. If you have an LA crate, those are the rockers it should have.
 
so i guess those rocker arms on back order -__-
 
You can just put stock arms on it. Summit or your local jobber parts store can get them or has them for the same money. The MP ones used to be visibly thicker than stock. They havent been that way since the 90s.
 
If ya need some stockers, I have spares, PM me if you want them.
