I think there is a good crossmember thread on here to search up in this part of the forum, can't remember if it covered doublers or not. I was gonna try and just fit two OEM crossmembers... but have no idea if that'll work. Maybe you can skip the crossmember under the tranny to 203 and just move it to locate under the adaptor foot between the range box and 205.
Brad, if the adaptor is still bolted to the front of that GM203 and it only has 4 bolt holes for the transmission it will be 27 spline, if there are 6 bolt holes for the tranny it's gonna be the 32 spline.
