bought 57 chevy 3100 apache, need to identify trans
just picked up a 57 chevy apache. says 3100 on the fenders but guy i bought it from says the body parts are from three different trucks. although the motor, trans, and chasis are original. is there some kind of ID on the trans that can help me figure out what it is? i know its a straight six stovebolt motor, but it could be the 235 or 261.

find the vin tag # on the front drivers door frame
find the vin # stamped on top of the frame behind the steering gear
find the vin # on your title

go to 47-59 parts catalog page 9 to decode your vin tag number(s)
all your vin # should match; at least the one on your title and a body number
post your results in the 55-59 chevy truck thread in this forum along with a couple of pics.
we like to see new projects all the time.

there was only the 235 6 cyl offered and 2 trans options; 3 on the tree and heavy duty 4 speed. i've never seen a 4 spd in a 3100 (unless it was a napco 4x4) but one of the guys in the above thread says he has one and that it is stock.

55 to 59 used a lot of similar sheetmetal on all those trucks; fenders, hoods and emblems were most of the changes from yr to yr.
all the cabs were the same some had big window, some had a small back window.
all doors and interior were the same depending on options order, of which there were few.
all the beds are the same: short step, long step, longer step, cameo 55-58 and fleetside 58-59
the big differences were the frames: all 3100 (1/2 t short) are the same and every part is available for this series truck.
make sure you have a 3100 frame before you buy any suspension parts or mods.
buy a factory assembly manual from lmc, it will be your build bible.
