465 was 68-up
420 phased out in 67
some of the shifters i have seen appear to be a little smaller diameter than others, seems like older years were smaller, like 60s and before
the SM420 began in 1947
GM called the 465 a CH not a SM in models like the 60s C50 trucks ill save the glovebox from this one we have,
CH465 is what ive always been calling them, and some of my gm options sheets list it as CH too, i read soemwhere it was CH for chevrolet but i dont know how true that is
dunno if any of that helps, but good luck
so 89 1 tons still have 465 ? hum interesting, i been trying to save up for an 89 1 ton dually here i know of for cheap, hoping i can get it in near future before it gets cut up :/
seventy4: i like oyur signature info, that was good reading, big time /forums/images/graemlins/laugh.gif so true!@
