Trans crossmember question.

[rs74]

On my 85 short bed, if I leave off the passenger top bracket to the crossmember will it really be bad for it. I was thinking about doing this in hopes to be able to run my x pipe up and over the crossmember on both sides. I have had alot of cars that the trans crossmember only bolted to the bottom flange of the frame and never had a problem with them twisting or anything. I have thought if needed then I could build a brace that goes from the bottom flange of the frame where the crossmember bolts up to the top flange.
