Default 4l80e cross member

I need a crossmember for the 4l80e i'm swaping into an f-body. Does anyone make one that lets you mount the torque arm to it?

I have read MWC crossmember requires the use of a short torque arm, which I don't want to do. Also the BMR one doesn't look like it has provisions for the torque arm mount.

My BMR cross member fit fine. I had to trim the lip of the pan but it wasn't bad.

BMR and Yank make a 4L80e crossmember with an option for stock torque arm mounting.

I asked MWC about that "option" and Eric said there isn't enough room to run the stock torque arm. Could this be an up-sell into his torque arm? Possibly.

I haven't had the chance to visually see the clearances myself just yet. But I will note that "most" that run 80e's have aftermarket torque arms of some kind- all chassis mounted.

As far as hacking up a stock 60e crossmember, I haven't seen anyone do that for an 80e application since the 80e is longer than the 60e. Anything can be done with a welder and some metal though.

My BMR fit perfectly fine. They have since fixed the issues that some were having.

We have definitely fixed the clearance issue with the BMR 4L80E torque arm relocation crossmembers that we had issue with a while back. The 4L80E transmissions are so big that everything has to be positioned just right to make everything fit without any clearance issues. As far as I know we have taken care of everyone that has contacted us with issues on the 4L80E crossmembers.
