What can I do that's cheap?

I just looked over a old hot rod article about this and was curious if I could use the springs out of a msd distributor to put in my mopar distributor? We have a few old msd units sitting around from my dad's mustang so that would make it very simple.

Also right now I have my initial timing set at 15 and my advanced is 34. With the lighter springs will it want more advanced timing in theory?
