I have them on my 72...
These braces are wonderful products. They are FAR superior devices to the turnbuckles that MSA sells. I originally bought one for the rear of my car. The part was easy to fit and it looks great. I figured the product would work well by design, but the finish quality surprised me.
After getting the rear one, I decided to replace my MSA front bar. The MSA bar is a piece of crap that should never be purchased. It literally is a ball-end turnbuckle. The hardware for the MSA part is also awkward. I stil have yet to find the size for the allen head harware. It's not ASE...it's not metric..WTF!
Some will argue that the TEP front bar is not a good idea because it is not legal in either SCCA ITS or SP because it is triangulated to the firewall. This is true.....but then again my deisel crank isn't legal either.
I'm not going to tell you that TEP is in any way a good company. I haven't had any experience with them from a technical point of view. Their customer service does leave something to be desired. These bars are built as they are ordered, so expect a 1-2 month lag on getting it.
