it's about the same as the exterior.. but it has bends, making it stronger... the prob is, it's a lot of area that meets up with the support... you wouldn't be moving it much... whether a short 2 x 4 and heavy hammer with it laying on a blanket is gonna hurt the outside, don't know...
how tight is the other side?
The other side is tight and close enough...the gap is acceptable on that side...so I would only need to do it to one fender.
Do you think that one "stretched out" while it was in the parts yard for years? Or it was just made different?
