Radiator Support Factory Part Numbers

[longhorn70gmc]

Hello All,
Does anybody have the part number assessable to verify and post on here for me on 67-68 front radiator support and the 69-72 front radiator support? I am also looking myself. I have not been able to locate yet on both of my trucks. I remember seeing one on the new out of the junk yard support I installed earlier this year on the GMC.
My Dad is building a 1969 4x4 SWB truck and already has had issues with the motor not lining up and now he is working the front Rad Support. The issue, the support is not lining up correctly with the factory frame mount holes; about an inch off. The current support he is using came off of a 1969 Chevy 1 ton hauler/supply stake bed truck.
If I was back home I could better verify this for my Dad, but he is in Ohio. I have this funny suspicion that the frame is not original and possibly off of a 73-87 SWB Chevy or GMC. I am basically trying to figure out what is wrong and appreciate any and all help. Thanks for the feedback and help!!
