I removed my crossmember. I had a custom built one made for dual exhaust. Early 3/4 and 1 ton trucks had a factory dual hump crossmember.
You can buy an aftermarket crossmember and make it fit.

Check my website for pictures. Look under the transmission and exhaust pictures. Sorry the site is blocked from this computer or I would post the pictures.
