Re: IML: 67' No Brake Light Issue...

Thanks for the advice! I've managed to track it down to the T/S switch; current to but none from. I have a friend who has the knowledge & the tools to do this the right way. (personlly you couldn't pay me enough to attempt this, between the tilt/scope & that blasted collar removal issue).

BTW, I actually have 2 brand new T/S switches, one of which I will give any interested party a gerat deal on, provided that it's not needed to replace a possibly defective 1st replacement. (Murphy's Law & all)

Anyway, I'll keep the Club posted on my progress as the care will be at my friend's place in a couple of weeks.

Again, thanks so much for your help & the cameraderie between us "Imperialists"!!
