71 fender to core support braces
 

My 71 did not have these braces when I bought it. I am in the process of a restoration and need to know if they are different from later cars and where they bolt to on the core support and fender.

Thanks

70 - 72 Fbody cars did not have that brace.

The braces showed up for 1973 model year cars;
The rad support was changed that year to accommodate depressions where the braces attached.

Along with the fenders themselves

Thanks everyone.
