Coolant system refresh is under way.
Made some block off plates for the water pump and thermostat openings in the block then added a new style block drain.

The large drain fitting on the left is the stock 40 drain, then a stock 60 drain and the new style on the right. Put the part number there for any one interested in getting one. Same part number works for both the 40 and 60.

I also added a lower hard pipe to replace the early style coolant hose. Mine had the hose bracket missing so this was an easy solution from a later 2F.
Next step is to fill with vinegar & let sit for a couple of days.
