So I have collected a hand full of odds and ends over the last 10 years. I have a 1979 Truck and frame. I have two Dana 60's from a 97 Dodge 2500 donor truck. I have a fuel injected ford 302 with 4 speed manual trans and transfer case. My question today is. The Axle is set up for Coil springs. Would you go for leaf springs or coil?and what available kits might help with this.
