Thanks for the great advice all!
I'm in the Temple area so I can check out Kings. I thought about going up to Western Star or Freightliner too. The Napa in Killeen says they aren't a medium truck shop, so they don't have any in stock. There's a salvage yard south of Belton that has a few buses in their yard that I thought looked promising...
I'm sure there's a motor sergeant on Ft Hood that could part with a starter or two
(p.s. NSA, I was kidding about that. please don't monitor my phone now)
so far rdbishop is in the lead for that warm beer!
