help body mount differences

[1972BackInBlackC10]

so I need new rubber or urethane mounts for my cab and radiator support, the problem is when I look them up it lists 67-68 and 69-72 is there any differences in the mounts? is it just the rad support mounts that are different because 67-68 are different rad supports from 69-72 or are the cab mouts different as well?

I have a 67 chassis but I have a 71-72 front clip on it and a 68 cab and the gaps on the fenders wont line up with the doors so I need to get new mounts and want to make sure I get the right ones, if anyone can point me in the right direction that would be awesome thanks
