Putting pistons in my 383. Seeing trouble with rod bearing

File/grind the side of the tang so that the shell is moved over slightly. The tang is just there to aid installation, it does NOT hold the brg shells in place. The crush is what secures the shells.

I have had to grind a LOT of brg tangs that are used on H beam rods because the slots in the rods are narrower than stock rods & the shell will not fully seat without grinding/filing.
