Hey All,
I need some ideas on how to adapt an original tail light lens to an aftermarket tail light base. I would like to leave the original nuts (with a straight screwdriver slot) as is and insert a stud with the correct original size and thread. Any help appropriating two studs and some nuts to attach same to the back plate appreciated. Or, any other suggestions appreciated as well. This is on a 1963 Rocket Gold Star. Thanks in advance for any replies.

The easy way is to cut the heads off the supplied screws and cut a 4BA thread onto those ends.
Screw the studs which you now have into the threaded bosses, maybe a drop of Loctite, and there you have it.

Thanks so much for the info. I had no idea what thread I would need or what those threads were called. Next question is, where would be a good place to purchase a dye or a set taps and dyes for BA threads and what does BA stand for? Thanks again, Trevinoz.
OK, I just found the thread chart in the technical section. So BA stands for British Association and these thread sizes are used for the smaller sized screws. The last remaining question is, where would be a good place to buy a set of these taps and dyes?
