sorry i'm not up on the correct lingo, if you aretalking about the rad core support that the grille bolts to it will work. i thing the 63 has one less mounting hole for the grille but you can just use the 3 others on each side and it will work fine. if you mean the supports from the fenders running up to the core support i think they will interchage as well. good luck, if i'm wrong you can have your money back!
