Stretching a pickup frame

[chunkypeanutbutter]

Pulled a stalled build off the shelf today. Ford Flareside pickup, the AMT/Ertl kit. Chopped the rear half of the frame off with the intentions to stretch it and make a wedge or flatbed race hauler.

What should I make the sections for the stretch out of? I was thinking flat plastic sheets, piled up with glue in in between each, let it dry and then cut to shape, but is there another way you guys do it that's better?

Thanks.

I used rectangular tubing. I made it longer so that it would fill in the whole length of the rail section. That way the frame wouldn't bend at the joints.

That should work well. Be sure to put some cross braces in as well.

I prefer using laminated pieces, too. I've found that sometimes, the thickness of the rails will be a dimension not available in rectangular stock or tubing. By laminating it, I can control the dimensions. Also, you will want to either pin the extensions or make some sort of locking key in them to maintain the structural integrity.
