I have the PC that comes with it's own polishing pad connected to a backing plate. Could you use any backing plate as long it's the size ment for the PC. Like I saw a velcro backing plate at a auto part store that is from 3M. It's the hookit model. it also has the velcro on it. Could that be used on the PC.

Keep in mind also the size of the backing plate in reference to the pad. You do not want a plate that is too large for the pad. You want a smaller plate than pad, so there is room to give around the edges when your working.
In addition, there are several types of "velcro"...Some attach better than others to specific pads. Try to stay within a system...Mike Pennington

I'm pretty sure that the 3M"hookit model" is proprietary to 3M, and you can only use there pads with it. IMHO, that severely limits your options
In this case, I would suggest that the internet is your friend. Order online, buy what really works...

~One man’s opinion / observations ~
Jimmybuffit is correct the ‘Hookit’ brand will only fit 3M foam pads.
Backing Plates:
Backing plates are fitted with Velcro to enable attachment of Velcro backed foam pads. To change the backing plate use the flat spindle wrench PN 69200 supplied with the machine, to hold the centre spindle and rotate the backing plate counter-clockwise to loosen or clockwise to tighten, turn the backing plate no more than a quarter-turn once seated, do not over-tighten.
Lightweight moulded flexible Urethane backing plates are superior to the more ridged and heavier backing plates commonly used. The reduced weight doesn’t produce a high torque for the motor to have to overcome. It also eliminates any high heat build-up when transitioning over contours or when working close to the edge of panels.
A 5-inch diameter backing plate when used with a 6.5 -inch foam pad allows a 0.75-inch ‘safety’ margin’ between the edge of the backing plate and the foam pad. To ensure compatibility of fit with a Porter-Cable the post adaptor should be a 5/16th-inch-24 threaded shaft.
