First start after 35 years

What a great story. Amazing what water will do.

Very similar car ownership indeed. Never had to deal with the enclosed drive shaft. The STi was a nice car. It found me; got it from a friend when the engine blew.

I've been doing some research on an oil priming tool, and can't quite figure out what's needed.

Many threads on FABO talk about a 5/16" hex (and making versus buying one). When I talked about it with my father-in-law, he said the distributor (with dual points) has a rectangular tab at the bottom (similar to a large standard screwdriver) to drive the oil pump.

Pictures of 1969 340 dual point distributors for sale on eBay show what looks more like a large standard screwdriver at the bottom than a 5/16" Allen wrench. I also looked for an oil pump priming tool at Summit Racing and at Mancini and both describe the tool as a 5/16" hex. I'm so confused...

Does anyone have better insight or experience on the oil pump priming tool we'll need (i.e. rectangular tag or 5/16" hex)? When I go to Illinois, I'll only have 4-5 or so days and may have time to order a second tool. Got to get it right the first time.
