It looks like you need an exhaust spanner, and they can be hard to find. If you can get the Russian tool or a copy from Jill, I would recommend it.
In a pinch, you can order a 2 1/2 in. Armstrong pin spanner, #34-219 (McMaster-Carr no. 5475A17), but you will need to bore out the existing 9/32" pin and replace it with a 5/32" oil-hardening tool steel pin. Fortunately, the pin in mine was not too hard and drilled out easily. For maximum strength, I chose to silver-solder the new pin in place. However, the high heat from silver soldering will anneal the steel, so it must be hardened and tempered to keep in from bending in use. While the pin was still red hot from silver soldering, I quenched it in oil and then tempered it to a medium blue color. It has worked fine. If you would rather skip the heat treating, it might work to soft-solder the pin; the low heat involved would not be enough to ruin the temper, although the strength of the joint would be much lower.

We just got a 2 1/2" pin spanner from Wholesale Tool (www.wttool.com if a location is not near you), and drilled the existing pin out which was not that hardened to begin with.
After drilling the spanner to get a press fit, we then cut off a section of a drill bit (plenty hard) that was the appropriate size, and pressed it into the tool.
Be careful not to drill out the old pin with a bit bigger than the new pin (or bit in this case) will be.
Works fine and is very cheap to do.
