No one knows what size the bumper bracket to frame bolts are? Sounds like its trial and error at the store bolt bin then.
Member on Moparts answered me. The front bumper bracket to frame bolts are 1/2-13UNC. I bought these and the fit.
No one has details on making the vert door braces like in the pictures? Close ups of the attachment details? I had corresponded once with a guy at the Clark Classic shop about this, said he would send me the pics, never did.
