Changing 67-68 Radiator support to a 69-72

[yfs200p]

I did a search and found a ton of threads about people changing their 69+ radiator supports to work on a 67-68, but nothing about going the other way. I bought a whole bunch of parts from a guy off craigs list and it wasnt until i got home that i realized he sold me a brand new 67-68 Rad. support. I still have my original one from the 72, but i dont know if its possible to remove the headlight buckets from it and weld them onto the new one. Has anyone tried this, or heard of it being done? My old one is fairly rotted, and the one i picked up is brand spankin from LMC so if i could save it that would be nice. If all else fails i guess i could look for someone to trade with me...
