7.25 Sure Grip rear end-clutch style SBP

Shooting for the moon, I know. Looking for an early clutch style rear to go under my 70 dart. my peg leg is fine, but whines when I get it to highway speeds, and it has bugged me for years. 8.25 or 8.75 isn't really needed as its for a super sixed slant, and really don't want to add the extra weight if I don't need to since its my daily driver and I can use every mpg I can get. When I get some spare $$ I am looking to turbo the slant and the 7.25 sure grip would be ideal for that application. Let me know what you have, I'm open to shipping on this, as these are hen's teeth nowadays and aren't going to get any easier to find.

Thanks FABO!
