96 Brake booster to 94 problems, help

I have a 1994 XJ without cruise control or ABS. I got the Booster and master cylinder from a 1996 XJ. The problem I have now is that the brake lights are on because the rod is about 1/4" too short to activate the brake light switch. Any suggestions?

After messing around a bit, I learned that the 1994 has an adjustable brake light switch, so thanks for all the replies. What happened to MadXJ's website?
