I tried renting, and then selling the drill/tap fixture, and it just got to be too much of a hassle, even when I included a 2-page step by step instruction sheet with the kit. I was barely breaking even on parts cost and machining time. If the crossmember clearance is a problem, just unbolt the front motor mount and jack up the front of the engine a little bit. If you put a hardwood wedge between the clutch pressure plate and the bellhousing, you can drive the new balancer on with a piece of pipe and a BFH without doing any damage to the thrust flange on the #3 main bearing.
