[TR] Lucas Heater Switch

[David Friedlander]

Thanks, Randall.  I thought I'd pass along to everyone that their part
number 635-180
rheostat is a Lucas 78384 switch. Moss Sales wrote:

Apparently, if you ever need a replacement switch for your heater, plan
ahead.

The Lucas 73834 is a rarity and supply will be highly questionable, unless
you

repair what we have or improvise as Randall has described. Moss appears to

only have ONE available. TRF has them as NLS. Vicky Brit does still list
them,

however...


Just a heads-up.


Cheers!
