OD tranny hard to come by?

I am also interested in an a500 in my Dart. I calculated that with 24.5 inch tires and a 3.91 ratio out back that I would effectively cut the gear ratio down to a 2.50 for highway cruising. Unfortunately for now I can't afford the 2k for a 500 ready to go,....and I would like to see if one would go in an A boy without cutting the tunnel as my car is unmolested and would pretty much like to keep it that way.

I don't see how there's any possible way it'd fit cause like DGC said the O.D. section of the A500 is the same as the one on a A518. The main case on the A500 might be an inch shorter than an A518 but that's about it. That's not enough to make the difference needed to fit that O.D. unit in. Only way to keep from doing surgery is to use a Gear Vendors o.d.
