The car is actually smaller than a new challenger.
I had a choice of buying new chally, or building this car. The runner should be cheaper and will definately be different. Yes, weighs less too.

The tranny required a bunch of floor mods to tuck up and in to get the correct pinion angle. I had to make tranny crossmember. This may be different with a non-alterkation setup, but I am not sure. Rear susupension is stock with 1/2" lowering block and rear sway bar.

I will also post pics of srt chally seats, they required floor mods, as they sit very high with stock floor "hump" near the outside of floor pans.

Interior is really the last challenge, but I will drive as long as there is seats and seatbelt!
