k3smostwanted was the closest! its a REAR crossmember, from the FWD model. [it MIGHT house the rear gearbox/differential, but i dunno since i don't have a VR4.] i should know b/c 1) i took the picture, and 2) i just finished replacing the rear crossmember and other rear suspension parts. it wasn't that tough, but i used about 1/2 a can of rust penetrant, losts of brake cleaner, an impact wrench. other than that, just a little elbow grease and it was a simple job. so if anyone needs any work done, gimme a holler!
here's another picture for your viewing fancy...
have fun with this one!
