Thanks - the blue powdercoating turned out great.
Yes, I drove it for about a half hour.
8 HP predator fits perfect with a 3/8 plate underneath, with just cuttung a bit off of the bottom of the torque converter plate. Remove ~ 3/16, and you can get the TAV cover to fit, and the gas fill is just between the tubes.
The predator runs smooth, but it takes a lot to get the big tires moving. I'm a pretty big guy ~ 250 lbs, but I'm sure it will top out over 30 with the 9T gear on the TAV.
You'd be surprised how big the thing is and how you have to get used to turning / cornering & the handling.
I wanted to build somethign different, and I sure did & am happy with it. I am sure there is some tweaking to do though (but that is part fo the fun) !
