Tim & Greg....let the killing start! That is exactly what this cab was. I knew it was a automatic tranny cab soon after I bought it. I have already welded up the dash hole, and sad to report, transplanted the missing firewall section from my cab to the new one. I had to graft the piece that holds the clutch pedal felt gasket and gas pedal pivot..just like you said. I wasn't aware the Hydramatic cabs were rare.
