73-76 transmission crossmember...which side is the front?

[slammed48]

on the original trans crossmember, the holes for the mount are offset just a little... so there is a front and back side of the crossmember...bolting it in the frame backwards will move the holes for the transmission mount.

Without having to wait until trying to put the engine/trans in...Does anyone happen to know which way is correct? The part number is stamped on the bottom edge of one side.... Is that the front side or the back side?

Thanks.
