sure grip for 65 dart

I am a fan of the 7 1/4, BUT, as stated there is no supply of parts to repair/rebuild them. I ran 7 1/4 SG in my race cars for years, without problems.
I still have one 7 1/4 SG rear that I am rebuilding, with almost all new parts. The only parts not new are the spider gear shafts, and the housing, and gear/sg case. It only took me about three years of searching to find all the parts. Never did find SG clutches, but had one set left on my shelf. I have about $500 in parts in it. The only reason to spend that kind of money on a 7 1/4 is for a "correct" restoration.

PS: This rear was a 5.13, now 3.91
