I'm replacing my center floor brace on my 70 Cutlass Supreme thanks to a mouse but FYI, I got a CHL center brace, they break it down as 64-72 A body, it's way off. Welded nuts not on the correct side of the hump for seat belts, hump area way off. I ordered a Dynacorn, they break it down 64-67, 68-69 and 70-72 and the match is perfect. Not to say the CHL won't physically work but if your looking for a factory look, check out these pics.

 

Wow, I have always heard that patch panels or other repair parts were all the same, as in they all come from the same place, so just buy from whoever has the lowest price. I guess you have shown that's not necessarily true. Thanks for the info!

 

Im experiencing same issue onmy 72. Where did you source the dynacorn?
