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. 
Why not just use the felt ones Brett ? I just ordered puncabs from greg for my WH20 as the decals are abit crap near the legs

In answer to your question Pete, on all my machines I use the std grey ones i bought in bulk from Mark. But on my new STERN pinnys, I will use the pincab plastic ones with felt inbetween, because it looks the goods. Eventually, I will add pincab coloured plastic ones to all my machines with the felt inbetween etc. Talking about mods for a pinny, I am creating 2 x different toppers for the AC/DC pinny. I will make an extra few I think and will share them with AC/DC owners.
