Be aware of the height on these non-original bridge covers, and make sure it will work for your intended application.
I had bought one for ~$20 from someone a couple years back for my EB-3, and it wasn't tall enough to cover the bridge without hitting it. IIRC, it could work on my 76 if I use spacers under it (the bridge on that is pretty much laid on the body). Haven't tried it on the BaCH.
Just FYI, YMMV, etc...
