So I have the solid "L" shaped lower fender braces that were on my car but one is rusted and split where it mounts to the fender. I also have some of the "L" shaped braces with the rubber mount points for the fender, that I think came off a 69? Dimensionally they look the same... You think the parts are interchangeable?
Thanks in advance.

 

Look nothing alike to me. Why ask just try it.

 

I don't have the fenders back from my painter yet..just thinking it through first. I will try on the weekend when I get everything back.

 

Yes, the two designs interchange. The rubber provides isolation. The 1969 O.A.I. cars used the 1968 design to clear the under bumper scoops.
