You never cease to amaze me Tyler. Have you taken a look inside that prototype ZF? I wonder if there are any major internal differences in materials or design. Just a general ? about ZF:
Was the ZR1 the original intended application for the ZF6 and was later adapted to L98/LT1 cars or was it other way around? Originally designed for L98/LT1 and then adapted for ZR1?
BTW do you drive that 89 prototype?
The shifter rod is broken on one end and needs to be machined; it is not the same as the later ones. I have not taken it apart Kurt White had it and rebuilt most of it. He also stated it was much more complex than the later units. Since the earliest units are ZR 1 specific I would surmise they were designed for the ZR 1 program then adapted to the other platform. The car is licensed and tagged but I do not drive it on the road. Its an 1988 built on the 87 production line in June of 87.
