I'm looking at two sm420's in a local wrecking yard. One is from a 1 ton, the other from a 2 or 2.5 ton.
Anyway, I looked at Pinhead's writeup and a couple others, but I see the two sm420's I'm looking at have a different casting by the reverse gear bulge. These ones have two horizontal ribs, one above, the other bellow the filler plug. Otherwise the trannys look the same. Oh, both have a parking brake drum. One is L213, (Dec 21 63 ?), the 2ton is K85 (Nov 8, 65 ?).
Will the lower rib interfere with the transfercase output if I use a plate adapter? It looks like it 'should' clear, but its hard to tell. Anyone use this setup?
Thanks
Martin
