First let me start off by introducing myself and saying im new to the website and to this fourm. I just purchased a Porter cable 7424 DA polisher and was wondering if someone could point me in the right direction for buying new backing plates for it. I got the standard size hook & loop plate for it but i want to get a backing plate that will allow me to use pads that are between 3'' and 6''. (possibly smaller if thats an option?) Thanks for the help guys!
