I have the old style PC 7424 and some Meg's Soft Buff 2 pads with matching backing plate. I want to buy some of the newer 4" pads and matching backing plate. While I'd like to buy a new PC, Flex, or G110V2, the budget won't allow. I've seen the Edge DA adapter at ADS but don't see anything that would work with my current pads / backing plates. My question is if anyone makes a quick change adapter of some sort that would let go back and forth between the two Meg's pad sizes without using the wrench. Any suggestions?
