7.5 3.45 Gear Set

I am looking for a new 3.45 R&P set for a '98 Mustang V6. It appears that the Ford Racing R&P (M-4209-L345) is no longer available (NLA). If this is so, which of the following would be the preferential alternative ... Motive (F7.5-345), Richmond (49-0042-1) or Yukon (F7.5-345)?


'98 GT equipped w/Koni, Eibach, Cobra R rims w/Yokohama tires, Cobra brakes all around & 3.73 gears. Also a Boss330 4.6 Cobra block w/PI heads & stuff from Accufab, ARP, Centerforce, Comp Cams, Fidanza, K&N, Mahle, Manley & Borla exhaust w/Mac Pro Chamber thrown in for grins & giggles.

7.5" 3.45 Gear Set ...

Toadster: "Why not a 3.73?""

I agree that the 3.73 is more common (& it's what I am currently running), but I need the 3.45 to drop the RPM. BTW, I purchased two (2) sets of the Motive R&P (F7.5-345) & neither one would accept the small OE pinion bearing due to the pinion shaft being 'out of round'. Also, FWIW, Richmond & Motive are the same company so some caution might be exercised when purchasing a Richmond R&P.
