I could go out and measure my Bulldog spacing, but won't have access to a tape measure until tomorrow.
I sure wouldn't spend $800 for new stuff. Be cheaper to have one of the old brackets removed and a new bracket installed at the proper spacing. The Bulldog kit comes with new brackets so you could use one of those. Bulldog is a great setup. I really like mine.
I got the Bulldog because I read several comments that the UltraFab were really slow. The Bulldog isn't real fast in the "high torque" setting, but it sure works, and is sooooo quiet. It never sounds like it's straining at all.
