I think you did good with the buy on this third member.. If locker does not work then you can swap posi unit... I have one of these units on order..
[QUOTE=Flash68;464775]Received another NASCAR part today...
Somewhat experimental (for me, not the part itself). I have always wanted to try a locker and now I will do so. Who knows, I may really like it. If not, I'll swap in a Tru Trac.
This is a Roush Yates Detroit Locker Cup Car take out.
Nodular case
3.25 big bearing
Daytona pinion support
3.64 gear ratio (the ratio I was looking for)
Gears REM polished
Gears scalloped/lightened
G-Force internal pump
1350 billet yoke
All this for under $1000 shipped to my door. And looks to be in excellent condition.
This 3.64 rear with my T101A trans will put me around 67-70mph top speed in 1st gear and 150-160 mph in 4th, depending on final redline of motor (figuring 7200-7500).
