Keep in mind and just to try and make it clearer;
there are 3 of the 4.80" retainers;
1 for the 18 spline BB trans with the 308/4.16" b.c., and
2 for the 23 spliners; 1 for the 307/3.70" bc, and 1 for the 308/4.16"bc
phew
and the od trans has the 308/4.16"bc with the 5.125 od
and the SBM trans has the 307/3.70"bc with a 4.35 od
and the BB 18 spl trans has the 308/4.16/4.80od retainer.
IDK about a BB 23 spliner, but I imagine it's also a 308/4.16/4.80
I think the 383 trans was same as SBM,but I don't know that.
