My 81K car has seen a couple hundred drag strip passes. I beat the snot out of it.

Bought the car with 62 K on it. Built it to do mid-tens and lost the posi unit at about 76K (replaced with an Eaton unit) and shaved 6 or 7 teeth off the ring gear about a year and a half later. Replaced that with a Motive Gear Ring and Pinion set up.


I got all kinds o' broken parts to display.
