    Hello. I would like to renew internal parts of the Lucas indicators fitted to my Commando, can anyone tell me what the small screw sizes are that hold the bulb holders into the indicator body head.

    Thanks Neil

    They appear to be 6-32 x 11/32 UNC (Pozi pan head).

    Agreed. I've also seen them shorter with no problem.

    But I've also seen original Lucas units that had screws with the same heads but with threads like sheet metal screws and I've seen lots of old after market units with that type of screw.

    Finally if the holes originally were 6-32 but are stripped, small sheet metal screws will work.
