Are the cabs, fenders swappable between a 1975 and 1980?

I have an old truck that I inherited from my Dad. It was his 'mountain truck'. I would like to bring it back to life and have found a 1980 1500 that I was wondering how well it would fit on my frame. On the flip side, if the cab won't fit on my frame, would my axles, etc, fit on it's frame?

Same body and fenders will swap from 73-80. 81 was where GM change the front clip. Some fabrication work would have to be completed for the clip to work properly.

There are many differences as far as the electrical components go, but if you are just using the cab itself, it's the same. The biggest difference that I can think of is the hole in the dash for the wiper switch is in a very slightly different location. Nothing that can't be overcome with a dremel.

Dad's truck was a total basket case. It wouldn't be bad to use everything inside the cab. I just want to make it look like his. With a few mods, of course, like a flatbed. Thanks.

Yes. 73-80 should be the same, I'm over after 1974 only minor changes. But if you were trying to put a 81+ front clip on a 73-80 you would have to completely change everything, Core Support, Inners, etc... I think even the Rubber Mounts.

I've found a front clip and box off the frame. Does anybody know how much they weigh?

Depends on how complete they are. Both can be easily moved around by two people.

Entire front clip, fenders, hood, cab with seat, and doors. And then the box.

The bed is in the neighborhood of 300 pounds, depending on length, stepside or fleetside and whether or not there's a tailgate. Front clip is a couple hundred I'd say, with the radiator too. I don't know about the cab.

There were some gotchas between 73 & 80.

73, & IIRC 74, used a smaller bulkhead electrical plug.

78-80 used a different wiper switch and wiper motor than the earlier rigs.
