Thread type on WFT576 reverse lamp

Post by **Andrew1967** » Thu Jul 09, 2015 9:35 pm

Simple question, I hope.

Anyone know what the thread is on the fixing stud of a Lucas WFT576 boot mount reverse lamp ?

Got one that'll soon be offered on here but would like to find a securing nut for it first, to make it complete !

Not UNF, looks a very fine thread ?!

Cheers

Andrew

I don't know the dia, you would have to measure it, but all the threads Lucas used for their lamp fittings were "Cycle threads" (BSCY) A tap will be available.

This for example;
