I don't know about the East Coast for parts availability,but here in Iowa,the parts are here,but you have to look for them. I know one guy,who has three '54,'55 1st-series 6500's,and two of the front clips are in good,to 95% excellent condition. The 3rd one was used year-round,until the fenders are literally falling off of the truck. How long is the frame of the '00 3500? Is it a dually? you may be better off switching the cab/front clip,onto the 3500 frame,(as long as engine/trans,are in good shape). If you wish to use your '55 frame,you may be able to graft the I.F.S./brake system, without "marrying" the two frames,which would more than likely be different widths. Same thing with the rear axle. With some mod's,it should be do-able. Just be sure to use the 3500 brake system,since the brakes are designed differently,for disc,and G.V.W. There's a recent post,here on the "Big Bolts",of a 2nd-series 2-Ton car hauler. It may give you some ideas on how to build your ramp bed! If anyone from N.J.(or close enough to be cost-effective),is planning on heading to K.C.,I could get you a front clip for maybe $300.00, (95% dent/rust-free),but you'd have to work the shipping cost out with whomever may be willing to work with you. I'm on vacation starting this Saturday (Aug 30),so ANYTIME between then,and Friday (Sept.5) works for me. Clip is located about 60 miles north of I-80. Welcome to the "Bolt"!! Sorry,guys,but he's "Moderated",and I couldn't send him a P.M. I'm not selling a front clip,myself. I just know of one available. I'm not in this thing for any money,just trying to help. Thanks for saving one from the crusher!
