Gene, I don't know if you checked with the local shops or not, here are a couple numbers from Winnfield. And here is the link to the page where I found the numbers, you may find some not too far from you.... another possibility, talk to Randy, aka Slab Hunter, he does a little machine work and may know a good shop that could do what your wanting.
