A flange mount radiator filler. Is there a junkyard source for something similar? Something that uses cheap off the shelf caps?
It would be over $40 to buy the filler and cap from summit racing.

How about $21? http://www.speedwaymotors.com/Garage-Sale-Water-Neck,52419.html
Caps are $6 to $20 at NAPA

Well, you could always cut one off of a radiator and weld it to a flange you make. It ain't easy, but it sure would be cheap.

Could you just use an expansion tank from another car? They're usually $5 from the yard.

Hrm... It's not as much cheaper as I'd have liked ($16, no cap), but if you're comfy welding aluminum (and IIRC you are), you could add your own flange to these.
Aluminum or brass radiator? Weld-on or solder-on, respectively? Does it need to be a bolt-on?
Seems like the grassrootsiest way would be to cut the needed section out of a junkyard radiator and weld or solder it into its new home. Yeah, it scares me, too, though after watching the roadside radiator repair on Bangla Bangers, I'm as sure it should...
EDIT: man, I think/type slow...

That's from a MK4 VW TDI. I got one from the junkyard for a whole $5.

You could always use something like this:
From a Dodge Dakota or Durango with a 3.7L, 4.7L, or 5.7L

I fabbed up a nice stainless expansion tank that is contoured to fit the side of the engine bay. The design places the filler in the most convenient spot imaginable (as opposed to having to use a funnel with a 24" flexible hose and complicated yoga positions like I have had to do for the last few years) I dont want to weld a steel filler to the stainless or braze/solder a brass filler because.....well I am kinda proud of the polished and tigged tank and I want it to be pretty. A bolt on unit would keep the pretty looks.
Buying an old radiator to harvest the filler cap from would probably negate any savings. the speedway piece is pretty but a bit more than the canton from summit. After cap and shipping it would be over 40 as well.
Motorcycle pieces look promising

What if you turned up a stainless collar with I.D. to fit around a neck and tigged that to the tank? Then you could solder a flangeless neck into that collar. You'd see the collar/tank bead, but the solder joint would be pretty well hidden...

I would pass on this as they are know to just explode for no good reason.

You can get them on ebay off of motorcycles. At least that's where I've found them in the past. I think I paid $3 for the last one.
