Short bed conversion - The 1947 - Present Chevrolet & GMC Truck Message Board Network

FNBasham · 01-09-2017, 04:41 PM

So I was looking to cut my truck down I know 20 inches needs to be removed does anybody have a good diagram of where to cut and what else needs to be changed besides fuel an brake lines and the driveshaft

Oh and on an other note if anybody knows where to get a shortbed stepside bed that will fit a 74 c10 please hit me up

14" between the front two bed mounting holes. How you cut is a common argument, but I went with a 45 degree cut myself. There really isn't a precise measurement from the front hole or back hole, just remove the 14" between them. The e-brake cable will need changed or modified and the gas tank will need to be changed. Either a short bed tank needs swapped in or as many do, a blazer tank can be installed.

So how much do you cut off the back

That seems to vary a bit. I cut about 3", but I haven't cut down my bed yet so it might not be right.

I've done three of these conversions and I've always cut about 3" off the back, I left as much frame there as possible to have room for bumper brackets.

So besides cutting and welding does anything else need to be removed and do I need to attach a new bed mounting point?

Also where did you get the shortbeds from you put on the swaps

daddyjeep · 01-09-2017, 09:43 PM

The bed bolts to the frame so...no, no new mounting points. I cut my bed down to a short bed. That is not the best route though. Find a used bed or buy all the parts from LMC to build a new one.

There is also a rear crossmember that can be moved forward. The holes were already drilled in the 1/2 ton I did but you'll need to drill them if you are working on a crew cab.

Shortening brake lines & re-routing or shortening electrical.
SWB specific gas tanks or aftermarket swap.
