I'm heading back home from work (although it will be dark before I arrive) so I won't likely put the hinges on tonight.
The best price, if someone else has Taylor Encore doors, which Taylor apparently no longer manufacturers, I've found for the lousy plastic hinges is $3 each (any hinge #) from this outfit in Denver Colorado (add a $7.50 shipping charge on the batch).
The advantage of the Taylor nylon replacement hinge is that no holes need be drilled in the garage door.
The disadvantage, of course, is that they're still crummy plastic.
I've already opted for 14-gauge steel universal hinges, from Home Depot, so this is simply a datapoint for others to follow.
