I have my round top carbs & linkage for the '74. Doesn't look like it'll be too difficult to swap the flat tops out (keeping the intake manifold)

In preparation for the swap, I started to drain the rad. Looked for the draincock and couldn't find it. Using a mirror, I located what looks like a brass nut with an allen wrench center where all the diagrams show the drain should be. I'm used to the drains where there's a butterfly-shaped "spigot" that you turn to drain the rad, and all the diagrams I've seen indicate this is what I should find.

Any idea on how to drain this darned thing?

The plastic drain plug probably bit the dust and the PO replaced it with a brass plug.... the plastic "wing-nut" drains had a short life span.....

You could just pull the bottom radiator hose to drain it, but it's a will make a big mess unless you have a large drain pan.

You'll probably find a few more "odd" things that a previous owner may or may not have done....:ermm:

I've always replaced the plastic plug with a brass petcock so I never had to worry about the plastic plug twisting off the next time I tried to drain the radiator... pull the brass plug out after you drain it and replace it with a more "modern" drain valve.. Right now I can't think of the right size....

By the way... The spittin image of the original white plastic winged drain plug, with the channel cut into it for a clean draining is for sale, under $5.00 in the "Help" racks of most Auto parts stores. It's marked "Subaru". Both my Z and Roadster are wearing these plugs.

Are these a standard size? That way if they don't have the Suabaru ones I might not be out of luck.
