    Rear beam AT vs MT?

    Is the rear beam (it carries the steering rack and the back motor mount) different for an automatic transmission car than for a manual?

    I know the motor mount is different.

      IIRC the only difference is 3 or 4 bolt for the rear motor mount.
      93 Ex i know for sure use 4 bolt.
      LX and DX use 3 bolt

        it is the same "crossmember" and all of them have 5 threaded bolt holes to fit both styles of rear mount.

          Thanks! I forgot that I had asked this question. I found the thread while searching for old threads that might have addressed the same issue! d'Oh!

          We got hit in the front right corner. It would have pushed the front right wheel in and forward. The mounting points on the rear beam were messed up, so I got one from the JY. It was off an auto-tranny car. I swapped the motor mount out. At the next race the front LEFT axle pulled out of the inner CV boot twice! I haven't had time to take it to get an alignment. The body/frame shops want to see the numbers from an alignment before they will talk $$ to diagnose. I'm assuming it is a bent chassis. I can't for the life of me find what is wrong, or figure out why this is on the opposite side from the accident.
