                It has full tubs in it, stock frame rails, ladder bars and coil over shocks.

                the 8 3/4 has been narrow 2" on each side, there is plenty of room for bigger tires but i need to get rims with more backspacing, the center lines on the car have 4 7/8 ...really needs 5.5 or 6 BS to move tires in a bit....

                if you minitub and move the springs and with the correct back spacing you should be able to get a 10 inch slick on your dart.

                Guess it's finally my turn. First run off the trailer with new combo: 11.12 @ 118.6 and 7.02 @ 97 mph!! I'm still high!! I didn't get to make any other runs as I don't have a rollbar in my full interior street driven 68 Cuda notchback! I was totally blown away, but I knew that when I had to hold on to the steering wheel because it left so hard and pulled in 3rd on an Indy Headed 440 64 Dodge Candymatic clone I was in for a good run. I had people coming over scratching their heads, and to be frank, I was too! Dam this feels good!!!!!!:toothy10:

                68 Notchback Cuda, full interior, street driven
