Tks for the reply's , if I can use my fenders I may do the swap , as the radiator has to be changed to go with the v8 I am going to use and I will be putting an IFS mustang front end under it so everything comes off , its going to take me a few years to save money and do the work as I am going to do major changes to this gmc as it is a 3/4 ton and I do not like that so front and rear suspension will be more modern hence why its going to be slow going as bills come first,,, I do like the longbed part but the chevy 54 grill is an appealing swap ,,next question is the hood to 54 chevy year specific or will some of the earlier ones work ?
