Which is why I tend to source parts from some odd places (hardware store, marina supply house, ...)
Maybe the local doesn't have it, but I can usually scare up something at least as good - if not better - somewhere else with a little looking.
If you get highly motivated, you can go nuts and replace the whole heater hose setup with copper - the picture on my site should be working fine, if you want to see how something like that would work (it's on a RENIX, I've added a hard tap for a garden hose to backflush, and the valve you see is there to force reverse coolant flow when backflushing without having to crimp a hose. The whole thing is nailed in with 5" vibration stubs between metal fittings, but I need to refine the design a bit.) Sweating copper isn't hard, once you get some practise - I think I fabbed that up in 30 or 40 minutes one day, but not with a good deal of precision. Still, it's close, and it's cheaper than using all of those moulded right-angle hoses.
I even made the new nipple from the water pump - used a pipe thread-to-sweat adapter, then sweated the rest of it together. Make it up into a right-angle bend, so I don't have a rubber hose running anywhere near the back edge of that idler pully (which I really didn't like!) and don't need a right angle there, either.
