Thank you, All. I was unsure of the availability of compatible systems
for a 5sp like in my 84..I guess I'll need to Google the Syncro lockers and
see how it is done there...If I could do that with little trouble and
expense when I have the case empty to rebuild....I would make my locker
controllable with a marine control cable..
I had 911 friction/clutch limited slips in my racecar...I think these
were rather simple and low tech, but I didn't have time to pay attention to
that detail when I was working that car...I do know that on a one minute
lap having a functional limited slip was worth about 3 seconds......a
rather significant difference.
.I had planned on AA Trans for the work but I am also now considering
German Trans in Bend, mainly because they are about half as far from my
location and said to do good work also.
