HELP - 83mm Piston needed

["Jack I. Brooks" <brooks@belcotech.com>]

I am patching my currently installed TR3A engine, while I am building up a
new engine to install in my TR3.  I had some broken compression rings, no
liner damage, but one piston has some hot gas erosion damage.  I'm going to
hone and re-ring, but I have to replace the one eroded piston.

I am looking for a 83mm "G" piston.  It doesn't have to be perfect, just
serviceable.

Thanks,

Jack
