18 VS 23 spline

WOW that"ll ruin your day. I've been thinking about Dana as well over the 8 3/4. I like to build it once and right.
Actually my day was made the race before that happened when I put a Ford Mustang automatic on the trailer in the first round! But I have A post on the racers part of the forum as I build my "budget Dana 60"...
I see it on the garage floor and get a chuckle - every part of the car is for my amusement \\:D/
