I have a friend who will give me his 1992 truck. I have two 1952 chevy 3800 3/4 tons and a 3600 1951 1/2 ton. I'm just looking for the frame dimensions for the 1992. I have the ability to modify things as required I just would like to see how feasible this will be before I accept his offer. His truck is in running condition and is 4 wheel drive.
I have been toying with building an extended cab 52 and lengthening the bed to be at least 96 inches on the 52. This would make a much nicer driver.

Internet says it's 34 inches wide and either 237 inches long or 218 inches long.

I suppose you could test fit an entire front clip from a 1 1/2 or 2 ton truck. The openings for the wheels are bigger.

The 92 is wider but the fenders on the 52 extend quite a way past the wheel. Maybe able to adjust the wheel offset? We shall see. | | | | | Joined: Oct 2021 Posts: 6,826 'Bolter | | 'Bolter Joined: Oct 2021 Posts: 6,826 | Don't mess with wheel offsets. You run the risk of damaging the wheel bearings, especially on front wheels.

The old trucks tucked the wheels really deep inside the fenders compared to modern vehicles.
I don't know a better source for dimensions than the link above or just measuring it yourself, but I do think the idea has merit and it is plausible to me that it would work. | | | | | Joined: Jul 2000 Posts: 623 "MONGO" | | "MONGO" Joined: Jul 2000 Posts: 623 | Here's what I have for the 92 extended cab. https://photos.app.goo.gl/sxLUR2Br3jMQd65P7I've got a regular cab Longbed 96 that I plan on doing a similar swap on. I'm going to use a 54 GMC 2 Ton Front clip and bumper on it and I have a cut down flatbed from a grain truck that I'll be using for a bed. ~Mongo | | |
