What do I have?

[TheSasquach]

A little back ground. I Have been a Dodge guy my whole life, I have spent the last 5 years or so offroading Dodge Ramchargers, and just traded a '83 Ramcharger frame and running gear, for a running and driving '71 Chevy long bed " dulley"(?) with a manual trans and 454. What has me puzzled is there are no fenders hanging off the bed the wheels are tucked the bed with wider than normal wheel tubs and about 2 inch rubber fender flairs on the rear. I have'nt brought the truck home yet and dont have pics or looked in the glovebox for an option list. The truck is in fairly good shape with the usual rust in the rockers and cab corners, it was origionaly purchased and owned by a feed and seed company in South Carolina, and from what i can tell im the third owner. Any help with info and what to look for on this thing will be greatly apreciated. David
