Punter, u can stick the soft felt ones (grey from MarkC or who-ever else has them) and put them between the plastic pincab ones no problems.
It is only very thin and with the overall package being squuezed tightly with the leg bolts done up, u dont even notice they are there. I will be doing that straight away with my NIB AC/DC. Without the felt between , the pincab ones can leave an indented line when tightened up properly, hence adding the felt is a must IMO. 
I will try it this way also Brett as i wanted to have the yellow pincabs installed under the red legs as i like this look,as on Swinks, Ironman machine.I was tossing up wether to go with yellow or red but i think with the colours on the cab artwork the yellow will look good.If i do not like the end result i will have a spare set of the felt ones here and i will just have plain felt under the legs.Thank god i have a pinball trolley here as it makes doing all this a breeze.
