Gear Ratios

[effvee]

Good morning, I have had a Quaife ATB for about 6 years now. Within the last year, I had a Rhino Case re-worked. I had gussetts added on the bottom, and Rimco also up-graded the bearing saddle area (I think that is what its called ). I had hoped to use the 3.44 ring and pinion, only to find out the the Quaife won't take the 3.44. So my only other option is to go longer/taller on all four gears. This trans is for freey way driving. I had a 2332 being used in a 1974 late gear box 3.88, however at 75 to 80 mph, the speed was to much for the trans. I need taller gears, can anyone suggest a gear maker out side of Wheedle? For all four gears, the total cost is alot on my old check book
