Default How to identify tial wastegate with calipers?

I have a unknown tial wastegate and I want to figure out what it is, where should I mesure?

The exhaust inlet area is about 39.6mm close to the valve, the od of the exhaust after the vband flange section of the wastegate is 63.40mm

There is a piece that slips out when the flange is not connected, when that is out the ID of the valve area is 46.62mm, when that piece is out i can see through past the valve.

The aluminum housing also says TIAL SPORT and of course has the serial number which does not seem to indicate their part number.

BTW : I suspect the wastegates to be 44MM's, because thats what the box they came in was labeled as.

Ok I eyeballed the calipers above the valve and it seems that the actual valve diam is 44mm. Thanks for the info.
