Good morning guys, I have a chance to obtain a set of axles from a 1987 Chevy 3500 i ton.The front is a Dana 60 kingpin and the rear is a Dana 70 dually with a trak-loc?.Both are 4.10 gears and in decent shape.The rear measures around 62 1/2" drum to drum.Is this worth picking up as an upgrade for my 1978 RC?
