Hi folks
Getting ready to do a 6.0 into a this 1992 SWB 4x4 4.3 5sp,keeping the OE 5sp.The 6.0 I plan to use an early long flange 99-00 6.0 crank.I am trying to figure out which flywheel I need.From what i can tell there is several GM part numbers PN 12561681 fits a lot of 02 up 6.0 HD and 4.8
PN 12561755 fits 99-00 4.8
PN 12561757 fits 99-00 6.0

Any help would be appreciated.
