5' 8" and 160 lbs tops.
Shrimp-kins.
I looked him up and it said 5-10. The problem is, actors will lie about these things, if he really was 5-7 he would probably call himself 5-10.
By the way he was a 2nd degree black belt in Okinawan karate so he was in fact a real badass. I took Japanese karate for 2 years, basically the same as Okinawan. It is a fierce martial art.
