1970 Muncie Bolt Finish

[Allen N.]

I am rebuilding my 70 Muncie transmission and am not sure if the bolts should be natural or black phosphate. I am referring to the bolts holding the tail housing to the main case, the bolts holding the side cover to the main case, and the bolts holding the front retainer to the main case.

Thanks,
Allen

On October 26, 2015, Eric Davidson posted the following for 1966 bolts:

My 1966 Muncie data shows:

Front cover---------no marks or M -------------------natural finish
Side cover----------SBC-------------------------------natural finish
Top tail--------------SBC------------------------------natural finish
Long bottom tail-----L5-------------------------------Black finish
Short bottom tail----G--------------------------------natural

I don't know how many changes were made from 1966 to 1970, but Eric has collected a lot of data on Muncie transmissions.
