The RH trans will look like a normal 727 on the left side with the 3 wire neutral safety switch and will also have the 2 or 3 wire plug also. The RE trans will have a round style plug on the left side of the trans with 7 wires in it. I built the 727 in my 63 using all stock Mopar clutches and bands. Since I have worked for a Dodge dealer the last 24 years I have a few of the Mopar kits around. I added the bolt in over running clutch (sprag) and I use a TA reverse manual valve body. Other then the v/b and sprag all the internal trans parts are stock pieces and have been holding up fine in my mid 11 car. In fact the 727 in my boys Dart is built the same and I built it in 1996. It have never been apart as we just changed the converter when we switched the 383 to a 400. Of course you will have the overdrive on yours but if you only plan to run 11's or slower most of the stock internals will work fine. Ron
