I was told and have read that the lockers are more suitable for the strip, for street driving they engage and dis engage while cornering and are very load and clunky. I don't personally know anybody that has used one.
The tranny I have is a BW ST-10 with the 3.42,2.28,1.46,1.00 ratio. Will a 3.36 gear fit into the 8.2 housing? I thought I read some place that only up to 3.23 will fit. I guess I need to go back to the Eaton web site and look a bit closer at applications for Pontiac
