Ok here we go picked up my 77( thought it was a 78 at first) crew dually today, in tomorrow ill swap in the SRW axle that I already had from a previous project to get it rollin.
Plan is to lay body on 22.5" classic semis. Bought the wheels a while back just need to get them milled. Gonna have to swap out the cab but I already have a cab off a 89 2500 that has the newer style interior and wiring for power windows and locks. Also is wired for TBI fuel injection, so that might be going on the built small block thats already in the truck. as soon as I get some progress Ill post up some more pics.
