What Valve Body Is This?

[TRBO3.8]

I THINK IT'S A 1986 GN,BUT NOT SURE.IT'S MARKED CK3 OR KC3(CANT REMEMBER)

Doesnt sound like a valve body from an 86 or 87 Turbo Buick. Marking on the valve body would be BR3 and would have provisions for 2 pressure switches. Other non Turbo Buick valve bodies would have provisions for 1 switch.
