Brake light switch -wrong part

[Mid Mod Guy]

The brake lights no longer work on my 63 Avanti. I checked the fuse, it looked fine but I replaced it with a new one. That did not solve the problem. So I ordered a brake light switch and went to install it and discovered that the threaded part is too small in diameter and does not fit or match the old part. I checked a couple different sources and they all give me the same part numbers and the same part as the one I already have in my hand. What’s going on? Is it possible? I have a non-standard master cylinder? I don’t think so. Here’s the new part that I have that does not fit.

Get one from Myer’s Studebaker, Nostalgic Motors or Studebaker International…at least you’ll know they’re correct.  Also…you may well need to bleed the brakes after opening the system up.  
 

The best thing to do is convert it to a mechanical brake switch.

If you have a replacement MC it could be metric threads and you will need an adapter.

Yes, the reproduction ones have a larger threaded hole for the switch. Just get a ateel adapter at the hardware store.
