TAIL SLIDER / GROW WORKS MST XXX-D Products

Seems Tail-slider is making parts for MST XXX-D's are they the first to make aftermarket parts for MST chassis?

That has been one of the things that has put me off the MST chassis is that every chassis is the same,no options to really customise to make your own.It will be interesting to see what other product tail-slider release.I'm Sure there will be a few XXX-D owners out there that will want to get their hands on some of these parts to set their chassis apart from the rest.
