I would think that would drastically change the caster looking at the spindles. That said, I already have the correct ones on my Challenger since it is '73. I was just hoping someone could use the ones from the 300 if I picked them up.
Thanks for the links. The Hot Rod article that I linked looks to have the same table as the ones you linked. Either way, it looks like the 300 spindles would be good for someone to use, and that was what I was wanting to know.
