Where is reverse?...

A '67 2-door post coupe is sure hard to find these days! Good for you! You got some very good responses from Mopar fans too. A '71 Cuda is an E-body and your '67 is an A-body. The E-body 4-speed is not user friendly in an A-body because of the mount and the length of the tailhousing. The E-body trans is a bout 20 lbs heavier too. It would require a much shorter custom driveshaft to be used in your car. As another person told you, E-body four speeds have dual shifter mounts. This was done so that the same tranny could be used in the '70 and up B-bodies (like a Roadrunner). The reverse ear on all the New Process 4-speeds is at the lowest position and at the rear. The shifter arm runs from the shifter UNDER the transmission mount to the ear. When the ear is in the proper position (down), you push the shifter over towards your leg and then forward toward the dash. It's the only way to go. The A-body 4-speeds are the lightest and they are super tuff! It takes a little more effort to shift 833s than a Muncie or Borg Warner but it is worth it. You can also go to BigBlockDart.com and get comprehensive information. Enjoy that rare little A-body!
