Hi Joseph,
Bill built my hybrid Getrag. Is uses the preferred ratio box, but the ring & pinion were swapped out of another unit to provide a more optimum top end cruise in 5th. I'd love to tell you what the RPM's in 5th are, but two (2) problems...
1. The car is back with the builder who is correcting the cooling system issue & some other nit-ipc things.
2. Since I got the Smith's Instruments, I do not yet have the correct pick up for the electronic speedometer, so I can't tell quite how fast I am going. But what I can tell you is it is a blast to drive compared to the demo I drove.
I wanted the ZF, but after common sense got a hold of me, I quickly changed my mind. The ZF unit is 40 some years old. I had a PAntera in the late 70's, and it was not exactly a joy to drive/shift. I cannot see paying a 5-7K preimum for an older box. I am quite pleased with the Getrag. I am obsessive compulsive for originality, regardless of cost, but was able to 'mentally' get past this one issue.
Joesph, let me know if any more questions & I will update you when I get the car back. If you want to PM me sometime, I'll call you on my nickel.
Tom
