Jim, my local Goodmark seller says there's are hit and miss. Inacurate bows and the gap can get wide. He'll go through several on a show restoration trying to get a perfect fit, or at least something good to work with. Not sure how many mfg there are for them.
I got lucky and found an original one on epay. I'm heading to Pigeon Forge in a couple of weeks, sometimes there's a few in the swap meet. Want me to check?

I don't have time for a job, I just need the money.
