Where exactly is the AR .48 or .63 marking on the hot side of an 86 T3 turbo? I've been looking over a motor I bought and can't for the life of me find any marking!

------------------
88TC, Gillis valve, K&N cone on VAM, MSD ignition box, coil, and plug wires, Hurst Mustang T5 shifter, 2 1/2" cat-back duals, trunk battery with disconnect, seguential taillights, more to come.

The ones I've seen have been marked inside the turbine inlet.

I just looked at the one I use for a paperweight on my desk. Its cast into the outlet next to the vacuum/boost port on the cold side. The hot side is cast just above the wastegate elbow. Very large and easy to see.
