Another option although it would be a bit of work is to adapt a standup target face to the arm. You'd have to remove the arm from the game which you'll have to do anyway, get your alignment correct and drill a new hole for the target face. Then rivet it on.

They make a million standup target faces. It won't be original but at least it would be in one piece.

If you look at the game now the rivet is not completely flush with the surface of the target. It doesn't stick out like a screw would but it does have some bow in it.

The guy in that thread who is making them looks pretty good. Flippers.com does have them as Lee posted but you get the whole arm, not just the target face. That brings the price up a bunch.

I doubt that PBR ever makes them. I guess you could ask them but that is a hot stamping deal and if he doesn't have the die then the cost probably exceeds the return on investment. Put it this way, if he's not making Gottlieb lockdown bars which have a pretty good demand he's not likely to make these target faces as Gottlieb is still his main business.

If he can do it I'll be happy to buy some off you. I'd love to have some extras around as the lower ones especially can take a beating.
