I wonder if any member can shed light on where to obtain a dimmer rheostat for my 4/4 1994 1800 instrument panel? I have been given a Lucas part number of 78526 by the usual supplier of bits and they do not have one in stock. They are thought to be possibly obsolete now. They also said Austin mini BMC 13h9027.

The usual extensive on line searches have not come up with anything.

Also if any member knows the resistive value of this dimmer I could obtain a similar rheostat and fit/modify one.

Thanks in anticipation.

Peter
