Since Mad Dog talks about "a Butfoy 5th tall gear", I would try the following address: Roy A. Butfoy 2824 S. Willis, Santa Ana California, 92705 U.S.A. Tel (714) 250 1798 Fax (714) 250 1281 By the way, the price that Roy Butfoy asked in june 1996 for a 3.77:1 final drive was US$ 2.400,-. Please keep me informed, I too think that a taller 5th gear would be an interesting solution to keep up the autobahn speeds without stressing too much the engine with constant high revs, and without sacrificing the acceleration because of a taller overall ratio.
