Ok ill start off by saying hi im alex im a new member here... ive read alot on this fourm and found it very useful. . Ok I have a 55 1st series gmc 350 hydromatic. The trans is no longer the hydromatic and was swapped out for a m420 sometime in the past. I had this truck giving to me and its rough but worth saving. The frame is actually in really nice condition but I need to find some front end sheet metal since everything for the cab is basically available. So my first question being. Where can I get fenders from? Second question. . Ive not heard of or read of anyone doing this but I have a 2000 gmc 3500 I just picked up and I want to use the front half of frame to marry to the original 55 frame. I dont want to here negative responses to this one and here its impossible because nothing is impossible. I have the other frame and I have the 55 ive got both for free and I love free I like the ifs front from the 2000 3500 truck has the big breaks and will make a smooth ride. My plans for the 55 is to make it into a car hauler ramp truck. Im thinking of possibly switching the rear from the 55 and running the 3500 rear also.. again big breaks and parts easy to find.. so all that being said I thank you and love the advice from this site
