[big job]

Just info; A 1981 Corvette came in for some A/C work and it has the piston valve set up
as picture Merc cruiser posted. Crank pulley, check with snow plow parts guys. If you
have a lathe or a friend that has one, its easy to machine a longer crank bolt. Back to
the Corvette, we replaced the leaking control valve > Napa had it. sam
