I am trying to determine the original frame rail thicknesses on a CJ7 ('85)
To those who are inclined to respond '1/8', I thank you for your interest.

I believe the outer channel to be 11 gauge, and the inner channel 13 or 14 gauge.

Can anyone confirm?

Thanks

 

I can't help but I am curious why you want to know what gauge it is.

 

I want to restore the frame to its original specification.

 

Ah! that makes sense, good luck.
