Talked to my transmission guy-------

But dont you have to cut with any auto overdrive transmission? Just less with some? What I have seen with the a500 or a518, there is less than a GM brand. Plus with GM you need special adapter to bolt it together.

I put the 200R4 in my A-Body. I did have to cut out a notch on the driver's side on the torsion bar crossmember, reinforced my chassis and fabricate a transmission mount. The method I used to adapt the transmission to my small block Mopar was to bolt on a Reid bellhousing with a small adapter ring that attaches to the front pump bolts of the 200R4 after the stock bell housing has been cut off. It makes for a clean, extremely effective, bolt on, 4 speed automatic overdrive with a one-wire activated lock-up converter that only engauges the lock-up in 4th gear.

There is someone who makes a crossmember braket that lowers the rear of the Mopar transmissions enough to clear the floor, but I would think the angle of the driveline is significantly altered when you do that.
