Re: removable trans crossmember
I performed one on my 87 Samurai. It also gave additional clearance for the front drive-line. What I did was used 3" pieces of 2" angle welded to the inside frame-rails. Then used 3" channel as the X-memeber, drilling holes and bolting it too the angle. Next I built a hanger off the channel for the tranny mount. This crossmember was moved to rear slightly, thus giving me more clearance for the driveline. This became a pretty sturdy set up. Also a stronger T-case mounting was fab'd off of it also. Let me know if you need some more information.
