Title: squarebody to late model frame?
Post by: robzkool2 on July 03, 2008, 06:07:17 pm
has anyone swapped a squarebody cab & bed onto a 99-06 frame?i have a 87 swb 2wd.the dimensions for both trucks are close and its something i'm pretty sure i can do.but has anybody done it?there is always something to slowdown a build and i'd like to get as much input as i can before i start.i plan to use the rolling chassis,computer,engine & drivetrain along with the dash assembly.i found a '05 single cab swb that has been rolled over killing the body.squarebodies are kooler anyway.any help would be much appreciated.

This isn't a popular retrofit as usually if one of those trucks are creamed beyond repair the frame is usually garb too. I'm sure with a welder and a tape measure you can make it happen though.

When I had my 64 C 20 I always thought it would be cool to swap it onto a 4x4, 92 or newer single rear wheel one ton chassis.

Now you're talking,  maybe some custom work to make an extended cab shortbed with a big back window 64-66, that would be cool.  If I could find a good fairly clean rustfree start I would take my 85 a part.

normally i wouldn't gut out a vehicle,especially one with a good frame like mine.and my body iz unusually cancer-free too.last spring i rebuilt the front suspension -from the rag joint to the tires - and parts cost a little over a grand with free labor(mine).but the rest iz toast.i did some math and it would be alot cheaper for me to do the swap as opposed to a rebuild.my 305 iz on its last leg,the th350 iz showing metal in the screen,and my diff iz roaring like a lion.i can buy the late model for $1500 with 45k miles on the clock.i do autobody & frame repair for a living.i'm just wondering if anybody found any bumps in the road.

The only bump in the road would be if the wheelbase is not the same, other than that sounds like you're up to the task.  Good luck, sounds like a fun project.  Just make sure the frame wasn't damaged in the donor truck.

Rob, As Vile mentioned, be careful with the wrecked ones. The new  frames are "Hydoformed" this design & the steel the frame is made out of makes them difficult to straighten. Quite often to get that new of a truck (& low miles) totaled, the frame being bent is how the truck got to the salvage auction. It is very common to have a dip &/or twist under the cab on a rolled over truck. Be careful, I see nothing wrong with the idea, just look over the donor carefully. Lorne

i hear ya man.  i wish ya all the luck in the world with it if you undertake it.  i'd just measure on that frame and make sure it's arrow straight before you potentially "waste" $1,500.

You can put all that stuff IN a 73-87...  You are looking at a lot of changes that isn't going to gain you much in my opinion...
