Burns Shadows Bass Tuners

Hello, dear colleagues and friends,
today I would like to ask for advice: I have an old Shadows Burns bass (1965) here and two of the tuners are missing the plastic parts so you need some heavy stuff for tuning the instrument which is not very comfortable on stage and probably anywhere. So I am looking for two of these tuners (right side of scroll headstock) and maybe somebody can help me with these. I asked Burns already but the answer was their todays product is not exact the same size and they sell only 4 at once and the price is pharmacy-like.
my email is shadows@impleo.de and I will appreciate any serious answer.
