I own a 1982 Dodge D150 short bed truck 1/2 ton with 8-1/4 rear suregrip with a 318 . it has the weak 3 leaf and short 4th leaf spring. Will the 3/4 leaf springs from 70's and 80's trucks inter change wether it be trail duster, power wagons , trucks ect? I know the leaf spring bolts might be a different size?

 

Sould fit. I would measure them first to make sure there not to wide.

 

Wow.. you got it all cleaned up..
stance looks good also…
keep chipping at it!!!
