Thanks Denny for the info. I didn't know the carrier changed in '51. So, I guess I'll either have to jury rig this '51 carrier into my '50 or sell it and try to buy the correct one at the next swap meet. I'm leaning on trying to shoehorn it into my '50 as is. I'll work on it next weekend.
Thanks also to Gmoniz for the link. Good discussion there.
I still would appreciate someone taking and posting a pic of a '51 spare tire carrier properly mounted (original). It would help me see where to bolt/weld the cross member.
Thanks again.
