Steve, I'm not really concerned if the crossmember is original GM although the guy I talked to said that he has seen them with GM numbers on them as much as I just want to make sure that it is a BB Xmember. Were the oval hole ones that you have seen aftermarket ones? This one has the original holes (slots) in it with no other holes so it isn't modified. Does anyone know if the holes in a SB Xmember centered in the oval opening? These holes in mine are about 1/2"-3/4" offset to the right like a BB should be. This crossmember has been in the car at least 17 years or more so I can't picture anyone having an aftermarket one out then since most of this aftermarket Phenomenon as being more current. In fact, I don't even recall anyone manufacturing a BB 4 speed Xmember at the present. I may be wrong.
