Strange PRS60T rear.
True Track, 35 spline 3.73, 3 channel and the aluminum cover upgrade.
It also will come with the custom chromoly SpeedInc driveshaft that is required to run the rear in a fbody. Less then 700 miles and no track time at all!
In my opinion this is the best rear available for 4th gens. Stronger then a 12 bolt by far and even stronger then the 9" setups.
$2100 for everything or $2000 with a working stock rear.
