What 9" rear are you referring to?? I've got a Midwest chassis fab 9 with their 3rd gen specific 2 piece race arm and cross member that fits like a dream

Only if you're using their motor mounts. I'm using that cross member on my 4l80e with an adjustable trans mount. I ended up cutting the TA mount off

Are those weld in? Was wondering if you can use existing torque arm and cross member with their fabbed 9"?

Re: 4l80E Trans Mount/Torque Arm

I have a moser 9” and an old Spohn torque arm and trans mount that is probably 18 years old. I am looking for a bolt in solution as I am trying to get the car back on the road asap, thanks.
