Hi new member 1st post.
Interested in purchasing 1948 CJ2A it has a fiberglass tub/body.
Inspected potential purchase today and saw body is supported with wooden cross members attached to steel chasis frame and wood liners in floors wells.  These all looked like premanufactured pieces.  My question, were there fiberglass kits years ago that used wood pieces to support the fiberglass?  Guessing this could be an older restoration? Which needs a redo  Thanks Steve

I don't know about jeep fiberglass bodies, but I am somewhat familiar with fiberglass reproduction bodies for hot rods (32/33/34 ford, 40/41 Willys, etc.). Using encapsulated wood in the fiberglass structure is pretty common. If the wood looks like it was there when the body was constructed in the mold, it is probably fine. It it looks to be added later, I would be suspect. You can always buy a reproduction steel body or even an original steel body if you thing the chassis setup is work the dollars.

I would certainly check for body cracks. Fiberglas will not flex as well as a Jeep frame.

Welcome to the page, SNOW5022!  Some 'glass tubs had (have?) plywood or balsa blocks embedded in the main structure for support, but the wood is not readily visible.  If you're seeing wooden support, Bubba has just used what was available with no regard for future deterioration.  This kind of "engineering" should be replaced ASAP.
There's a reason it's called Ol' Unreliable

Ol’ Unreliable,
That is my concern too.  Here a couple pictures.
Thanks Steve

That does not look right. The wood should be encapsulated in fiberglass to keep the moisture out and we would hope that there should be some rubber in there to take up some of the flex. I have driven some fiberglass cars and they are built to be as stiff as possible. They corner better that way. I'm not sure if a Jeep frame and a fiberglass body play well together unless you do it correctly.

Just do something to seal the wood. I imagine you have read up a bit about how some Jeep frames flex more than others. My MB frame barely flexed and my 3B frame flexes a lot. It concerned me a bit when I could see my hood swinging to it's limits In the big rocks and my steering wheel was moving side to side about a half of an inch each way. Frame flex.

Looks to me they just used blocks to create lift or bridge the gaps. Some of the glass bodies didn't follow the exact contours of the originals. So folks had to get creative. Not the best solution, but I've seen it before. 

I wouldn't disqualify the Jeep because of it. Assuming the rest of the Jeep is good. You can replace that with the proper body mount material.

what no fender said. I have a glass bodied flatfender. Just replace the kindling with proper body mounts. It really depends on manufacturer/ class of body. Generally there are light weight "race" bodies, regular and heavy duty versions. My AJ's body with it's encapsulated balsa and steel plates weighs more than a steel tub. Just make sure any roll cage is built to the frame .

Thanks for the numerous helpful replies.  Here is a picture showing how wood has been placed in the floor wells.   Glass underneath is not cracked or broken.  Who knows? Someone’s “good idea” from years ago? Frame seems solid enough.  So Maybe I will take the plunge.  Idea is a father son project. I am a reasonable mechanic but don’t know how to weld.
