Extended cab short bed to single cab long bed

[greenz97]

I Know this sounds really far fetched but is it possible? is the wheelbase the same? How about body mounts?

This would be a while in the future just really want a long bed for the stuff I use my truck for.

All that info is in the OE service manual, wheelbase measurements for all combinations. In body and frames section all the frame info.

They are close but not the same. Not only wheelbase but frame under the cab, and obviously body mounts. Could probably make it work, anything is possible...

I'm going to reverse that question.....kinda. I got a single cab long bed. Is it feasible to make it a single cab short bed? Prob a dumb question, but hey, why not?

Will have to stretch the frame under the cab. GMT-400 frames kick up after the cab, so not as easy just to move the mounts. Inless wanna notch the cab to fit the frame....

In my opinion, you should just look for another truck. Thats a lot of work and I'm sure you can find a good LWB truck that fits your price range.

Wheel bases: 117, 131, 141, 155.
O.P. wants to make a 141 into a 131, but wants to replace both the cab, the bed, rear driveshaft and all the parking brake cables, and wants to make major surgery to the frame?

That means he's only gonna keep everything forward of the windshield.

It would be MUCH cheaper to sell the 141 and buy a 131.

Edit: Back in the square body days, there was a conversion known as a Longfoot. I've always wanted a 400 version: ECLB frame, transplant a 2 door cab with a super long bed, somewhere about 12 foot.

The frame tapers in width from the front of the bed to the back, (think parallelogram) therefore it's not just cutting it front to back, but side to side too.

There's a 154 and a 155, and that still leaves out the 160something crew cab long beds. I forget which is which, and it's a nightmare sifting through it on www.car-part.com. It seems either GM mismarked some trucks and/or the guys at the yards reading the stickers are re-tarded. One is a CCSB and the other and ECLB. I also noticed the frames don't all kick up at exactly the same location.

Useless trivia as far as this thread is concerned, but I thought it was good for a head scratch.
