converting a longbed to a short bed - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ive seen people do this but I dont know how to do this. I have to replace all the rear corssmembers do to rust and I am going to replace the rear end, springs and relocate the shocks so i figure I may as well shorten it up. Im going to try to find a short box instead of cutting up my long box. How and where do you shorten the frame to convert it?

Does the 12" have to come out fomr under the cab" or can it come out from right behind the cab?

you need to come south and get a rust free short frame. I don't have one at the moment but I'm sure I can find you one!

I'm taking mine out from behind the cab. I am building a 4 link so I see no reason to cut the usual section under the frame. Also the section I am cutting is the wide section of the frame above the axle doing that I will gain about 2" on each side for more clearance. Just my .02

I'm just going to pull the cab and take it out from there. A local blasting shop will blast and powder coat my frame for $300.

300 bucks !!!! That sounds like a good deal to me.

As I read your posts I keep thinking what's ahead for me with my C10. Although my C10 is already a shortbed my plans to do a back half, narrowed 9" F**d rear end with ladder bar setup & "alter" the wheelbase by moving the rear axle 5" forward I will be watching this thread closely.

Good luck, take your time and post lots of pictures.
