can anybody tell me if the truck i have that has 8 leaf springs is a reg. p/u or a 3/4 ton .
. . .
A 3/4 ton will have 8 lug axles and single rear wheel, with an 8 ft long bed. the shifter will be on the floor and it will be a 4 spd. you can get a one ton single rear wheel, but I think a one ton will have more than 8 leafs.
1951 GMC light truck standard spring-set leaves:
front springs: 8 on 1/2 & 3/4 ton, 7 on 1 ton
rear springs: 8 on 1/2 ton, 7 on 3/4 ton, 8 on 1 ton
