I would be very intrested in some metal trackpads, as you may know i have a Vario/Fumotec excavator and there are a few more on here so im pretty sure almost all of them would like metal trackpads.
I could gladly send you the dimentions for the plastic pads i have right now, or even if needed send you a pad if you need it to measure yourself?
This would be the icing on the cake for me and are of course willing to pay a reasonable amount for them, let me know if you need more info!
Great idea!
Here is a pic of the plastic one, im sure this could be used on other excavators as well if you use the same pitch sprocket and idler wheel.
