gearbox identification
Posted: Sat Apr 08, 2006 7:05 pm
When I bought my '82 GTV6 last year the P.O. told me that he had replaced the gearbox w/ an N.O.S. unit out of a Milano. I found his receipt for the labor to install the tranny but not for the tranny itself.
My question is how can I figure out what final drive ratio it has w/o opening it up? I know for sure it has a LSD from driving it. So my thoughts are either a Verde or even better a Platinum Box. Are there any #'s on it? (I was under it today and didnt see any unless they are on top)
I was thinking that if there is no way to externally ID the box, that maybe I could put a refrence mark on the tire that lines up w/ a mark on the fender in chalk then put it in the closest gear that gives a 1:1 ratio (maybe 4th gear?) and turn the engine over and see what it gives me in tire rotation. Would this idea even work? Any way Im open to any sugestions and if there is no external way to do it Ill just have to wait till it needs a rebuild open it up and count teeth
