I got the same call last year and then got another call a couple of months ago saying my trans was ready if I wanted it. I think I was #381 when I originally signed up. Transmission installs just like the 833. I am running dakota digital gauges, so I had to buy a short extension for the speedometer cable to make everything work. Easy fix. The car is so much more fun to drive down the highway now! 1969 GTX, 525 horse 440, + 175 hp nitrous, 12" mcleod diaphragm clutch, 4:10 Dana, 28" tall tires. Ran 3000 rpm @ 60mph before and now runs 2600 rpm @ 75 mph. Still in break in period. 150 miles down, roughly 500 left to go.
