I'm still busy researching alternative gearboxes for my GTD (engine is a 302). I have narrowed the choice down to two, both based on the 3.44 final drive.
The UN1-013 was originally specified for the 21 Turbo. The other box, UN1-07 was specified for the Alpine Turbo. The boxes are very similar - ratios on 1st, 2nd and 3rd are identical, but the UN1-07 has slightly higher ratios for 4th and 5th.
My question is - has anyone else looked at the comparative merits of these two 'boxes, most particularly with their gearing on the road once tyre sizes are taken into consideration?
Any user experiences would be much appreciated,
regards
Peter
