Reproduction Tire Pump 1970 Commando S

I have been looking for a source on a reproduction tire pump for my 1970 Norton Commando S. I found some on VMCC, but I am not sure what length the pump needs to be.... Can anyone tell me what length pump I should get, also is there any other mounting hardware I'll need? I did a search but can't quite find the info I need.

DomiRacer used to sell one that apparently was close. They're gone so I don't know where they went. But I don't have your info, I missed getting one. There's a few guys on the forum that got one, pm or email Nelson he got one I think.
