has anybody every swoped out a 1/2 ton rear end and put in a 3/4 ton rear end on there 3100 series truck. ive got a guy that has offered to give me a 3/4 rear end out of a 54 or 55 chevy or gmc, not sure which.
it would be the open drive line then. it is the axe and pumpkin, springs and drive shaft. I know it would be 8 lug but i can deal with that.
will it swap ok. the problem with mine is i need a new tranny and i have 3 4 speeds sitting around. i've got the 3:90 ratio in the rear not sure what the 3/4 ton is. might be 4:10. i'm needing new or different leaf springs on mine as it sits to low in the rear even with out anything it it. the heavier leaves would help if mine are shot.
what do you think.
