Harley, your dollars make sense, to me it's not a dollar issue, if you buy 10 Dubro JR gold metal horns, only 4 of them will fit your servo "just right". I guarantee this, and have many examples here of them that aren't right.

Send me your address and I will send you 3 or 4 of them to prove it. There appears to be inconsistency here, and I've never had that with the HD nylon ones.
