Let me know if the cap solves filling. I'm planning to reuse my aero cap on my 1976 3000M it's straight out of BL in the 1970s and for the record doesn't fill quick either!
Also like the knob very OEM- how much?
Not used it yet for a fill but I'll let you know.
The knob is made by
Richbrook and IS OE on the Aero America. I paid £19.95 for mine from them direct.
