justin,
you know w/ your lift you should be running a DC shaft anyway
the GBR and tom woods shafts are both better than the later model D2 front shafts.
the Double cardon joint is bigger (spicer 1310) and the center tubes on both are bigger/thicker and both are greaseable. in addition, both of these places , as well as any drive shaft shop can lengthen a shaft to accommodate for your lift...
