I've got a (Bill Baghaw's)
Pro Parts Pinion Depth Checker for sale. It's the deluxe model that allows you to check the pinion depth on all popular rears such as the 10 and 12 bolt Chevy models, Chrysler 8 3/4" and Dana 60, 8 and 9-inch Fords, and others.
I purchased it 19 years ago and used it
only four times. Honest!
High quality tool. Excellent condition. $225.00 + UPS.
