    Does anyone know of anyone who has done this? I have sorta been looking for a junker bodied K5 frame to build into a buggy sorta affair, but no luck yet. I have a LWB 3/4T that is sittin here. Is it tough to shorten the frame to around 106-110", maybe take a length out of the center of the frame and put it back together? I am contemplatin either a tube buggy idea, or a pickup cab type/ flat deck but heavily modified. ie widened Jeep hood, no front fenders, topless etc. It will be a long term project, but just thinkin..... /forums/images/graemlins/smile.gif Usually bad news when I start thinkin like this...

    It's been done a lot, but I have a blazer and I am trying to lengthen my wheel base to 110-115, more stable and fits most of my trails.

    I shortened my crewcab longbed to about Suburban length. I took out 23 inches by moving all 4 spring hangers forward. Use a 10mm drill bit and 10mm bolts to put it back together. I used grade 8, but some people tried to tell me to use grade 5 so they would flex instead of brake. I would rather have the stronger of the two. [​IMG]

    Now that is cool! What is your wheelbase now? How do you find it on the trails? As compared to a Blazer wheelbase length? Is yours as long as a regular cab pickup wheelbase? Just lookin for a fun project to do that works well. Thanks for the pics!

    I have no idea what the wheelbase is. If I knew the original then it would be easy to figure out(subtract 23 inches). I still don't have it completed so i have no idea what it is like on the trail or road. I need a wiring harness, steering column, gas tank, front and rear shafts, and a roll cage at least.

    Ryan,
    Very cool idea. What do you plan to do for the bed area?

    FYI:
    73-87 long bed pickup = 131.5"
    73-87 shortbed pickup = 117.5"
    73-91 suburban.......... = 129.5"
    77-91 crew cab lg bed = 164.5"

    Cool truck. What gas tank are you going to use?

    You've got me thinking

    I was wondering what it would look like moving springs up and cutting out the wheel hump in frame. It's hard to forsee any clearance issues there with the lift in place. Your departure angle is gonna be great!!

    I was looking at the frame on the lwb pickup and see that it drops at the back of the cab and is a little lower from there forward. If a guy cut the frame, and welded it on straight, it would give the equivalant of a 3-4" lift... dunno if you caught what I mean, but I am cutting the bed off the truck this weekend and checking it out a little closer.

    BTW thanks for the wheelbase numbers. Might help!

    wheelbase would now be 141.5". The bed will be a flatbed made with 2" tubing for the outer edges and I am not sure about the bed surface yet. Going to put a tool box behind the cab and a spare tire mount on the driver's side that will hold the tire upright. Hoping on using a 40 gallon 'burb tank mounted just forward of the rear axle.
