Glad to hear!

UPDATE---Success, or Close enough to it.

I posted a want ad on row52.com and a guy from Mississippi went to the yard in Alabama (which had '79 210 intact) and pulled them for me (including the washer resovoir and pump and a bunch of hoses) . I hope he grabbed everything I need, but either way its a really promising start. This cost me less than flying anywhere that had these cars in their yard anyway.

They're en route and should be here next week. Hoefully this saga will be over soon. My only concern is dialing in the carb after reattaching all this stuff. I may have to post here for help, but first will rely on the service manual which appears to have fairly detailed instructions.

They are both necessary

Do you know if the upper and lower brackets are both necessary for the pump attaching or just the lower?

There are two brackets for the air pump:

1. Upper bracket (circle in your photo above) with Idler Pulley & adjusting screw
2. Lower bracket (in first photo)

The upper bracket differs A12 vs A14/A15.

Unfortunately I don't have any good photos of those parts.

I think that may not be it. I found reference in the 79 shop manual to the idler pulley bracket and the air pump bracket. Not sure if I put the emissions stuff back on if I'd need the idler pulley, but I think its the air pump bracket that is definitely needed. It looks like there 2 complete (more or less) 210s at a yard in Salt Lake City. I'm going there in 3 weeks with my band, may have to wait till then to give it a try.

I would post on Ratsun.net and ask if anyone who lives close to Pullapart will look out for one for you. Or if you need it sooner call Younker Nissan or another vintage-friendly Nissan dealer.

This is an idler arm. It's part of the steering linkage:

I've called all the places on the list with air pumps on car-part.com . No luck there. There's a complete engine in Colorado Springs (about 60 miles south of me) but they won't tell me if anything is attached. There's an 'idler arm' in NE (incidentally the same place where I got the air pump from) on car-part.com. Is that the right part?

Use the national hot line to find the part at a traditional wrecker. They will ship it mail order. There are 15 or so wrecking yards selling the air pump, so maybe one of them pulled the bracket with it. Phone numbers are listed. http://car-part.com

Or self-service yards. Currently there are 210s in wrecking yards in Washington, Oregon, Utah, Nevada, and one in California. But they are self-serve, so unless you can go an look they won't look for the part by phone (won't tell you if that part is still there). The one in California may be gone by now since they tend to keep cars only a few weeks.

OK that is the "idler pulley bracket". Be sure to get it with the pulley attached because there are three different ones.

Nissan wants $70 for the parts, but it will probably take weeks on order from Japan. Or maybe they'll have one in three days.
