Cheers guys, I'm trying to get the Blast sorted as well. I'll update on those when possible.
Update:
I'm still waiting on a final set of terminals to be delivered before I can start kitting these up but I have been busy in the mean time.
@wigsplitta has been a massive help and very kindly took the coin doors/mechs off his cabs and sent them to me to develop against

Big up
@markedkiller78 and crunchywasp[too for whipping their six inchers out for me
Mounts for E2, NAC and Windy 1/2 are done. It looks like E2 will also fit E3 (and possibly AWSD, juck checking that at the moment) and the NAC one should fit the Astro City too.
I printed the development mounts in black but I think white looks nicer so I'm going to go for that.
All kits use the original screws to fit the mount to the cab apart from the Windy / II that needs a couple of additional bolts/nuts that will be included with the kits.
Price for all the kits will be the same - £12
It's straight forward to fit all of the kits but I'll put together a guide for each one.
I'll update again once I have the final parts required, hopefully in the next few days.
