Factory steel gauge for tub???

OK so the next step is to buy floorboards and clear all the rust in the tub (there is a lot). So my dad and I went to this locally know guy who fabricates floor boards, side panels, etc. you name it for CJ's. But one of my friends tells me that the gauge he uses is not that strong.:?


So I wanted to know what is the steel gauge number for the original CJ-5 body. Because I'm going to call the fabricator to ask him what gauge does he works with.

Thanks in advanced

 

thicker is better......the lower the number the thicker the metal i would think 10 or 12 gauge would do fine.....Jeff

 

Thank you all... will work on finding the thickest one
