I sent some indicators to R Anchak but he is busy doing other parts I am sure he will get on to them I have some good PE400 airbox to carb boots I hope to get done I think someone said you can still get them but I think that is only the 250 and I would love a nos 400 one for my Z or a repro one.
I am making my own thermoformer I will be trying to make a few plastic parts very soon I have a heap of nos indicators but they are for my bikes so I might have some to help you out though if you are ok with some old ones.
