Rear Lights

[5296]

Hi,
I need to replace the screws securing the lens covers on the rear lights of my 1970 S4, and I'm struggling with their specification. The size is approx. 4BA but the thread is coarser than BA. Can anyone tell me what they are?
Many thanks, David.

There've been previous posts on this. Try this thread http://www.lotuselan.net/forums/lotus-chassis-f36/screw-thread-t21334.html for instance, or a search. They're UNC not BA.
I prefer the socket head screws.

Many thanks for the quick reply - and the thread leads me to exactly what I need to know. I think I'll got for the socket heads.
