Default bmr t56 crossmember 4l80 swap

So I just got a nice beefy bmr t56 crossmember with the torque arm mount put in my 02 trans am. Now im starting the 4l80 build. Question. Can the crossmember be used/modified or am I gonna have to sell and get a different crossmember. I want to keep the long tq arm setup. I have been searching for 3 hrs and haven't found info yet.

Without having them side by side it'll be hard for you to compare them and adjust.. And keep pinion angle the same.

Unless you want to cut your current one up and weld/fab it.

I don't weld yet lol, so I would sell it and buy the bmr 4l80e crossmember which will have the torque arm setup ready to go so you can reuse your long torque arm.

Your t56 one should sell quickly tho if you decide
