Mounting a 32 ford truck brake light switch

[kaleborgill]

I am looking to fix a brake light switch on a 32 ford truck. I mounted one to the frame where the old one was but theres something missing. Theres nothing in place to activate the switch.

Is it a big truck or pickup truck? On the pickup I believe it mounts on the transmission.

Would it be different from the cars?

Early 1930's Ford big trucks typically have the brake light switch mounted to the side of the transmission.
