Wastegate spring ID question.

I'm trying to determine what spring I have installed in the stock wastegate of my 79 Row 930. There doesn't appear to be any color coding or identification markings on it.

After a full boost run, my tell-tale needle is sitting around 1.1 bar. I don't know if it's seeing a spike at throttle release or what. The car has a functional Miller-Woods fueler installed, so I suspect that it may have something other than a stock spring. Regardless, I'd like to determine what I have in there.

Can someone provide the dimensions, coil count, and wire diameter of a known spring for comparison?

Or, it there is a better way, let me know.
