70-72 Bumper Brackets on a 73?

[asm74]

If I nabbed a set of front bumper brackets from a 70-72 challenger, can I use them on my 73?  with my 73 bumper chrome and reinforcement?
Or do I need to get the 70-72 front bumper as well?

I'd like to get the brackets and do away with the bumper fillers...

I also know for a fact that the 73 reinforcment will not work on a 74  a member sold me a 73 new bumper for my 74 and I could not mix the reinforcments.
