So you have a 51 Ford pickup on an S-10 frame . Did it start out as a fenderless ride ? Have you been riding around with the S-10 IFS exposed and have now decided you don't like the way it looks ? Cant say I blame you thsy do look rather XXXXX . Making changes along the way is done all the time . You think something is gonna look good and when it doesn't you change it . People graft various front clips ( Camaro , Mustang , Volare , etc.) on to different frames with out any problems . Cut off the S-10 frame and graft on something more to your taste . I have a 47 Chevy pickup that has a Camaro front clip , the portion of the frame under the cab is a 48 chevy pickup frame and the rear portion is a mid 80"s pickup frame . All welded nicely together to make a complete unit . Find the axle and spring set up you like and build a frame to hook the axle to the S-10 frame at the firewall area. Not exactly a weekend job , but when your talking about building a rod , it's not rocket science either . Go for it .
