Definitely don't rely on just this for a rebuild. This guy actually claiming that the HD version had a limited slip diff.
when did he say that?
99 Grand Prix old build- CAI, Custom exhaust, HV3, Stage 2 TB, custom tune, ported heads intense s1x cam, headers.
Nothing great Just a small T66 Turbo with a Hv3 On a stock tranny untill i finish the other one.
