Default 62 GG Transmission crossmember

Am putting a turbo 400 in my GP. Problem is crossmember will not go down low enough to attach to transmission. Besides modifying existing piece, are there any other suggestions? Is there another that would fit? Does anyone have something for sale? Help and suggestions would be appreciated. Thanks

I used an A Body x member with changing to 4 speed. Has two raised areas for exhaust pipe clearance. I did have to add 1 1/2” to each end as it is not long enough to span from frame rail to frame rail. Very easy in my case but don’t know how it may match up using your TH 400 but I think many a bodies used the same trans ....
