Brake Light Switch Tips

[glarkin]

Hi, I have replaced my brake light switch on my 66 Mustang GT and I always have trouble putting it back together and having the lights work. I realize that I must have the nylon spacer on the inside and outside and put in the pin to make it work, but is very hard to put everything on and slide the pin in. Does anyone have a tip on who to do it better or is there something wrong in what I am doing?
