It appears that there are several Marshall, Mesa, Orange and Egnater 2x12 cabs on Craigslist that would probably work great.
You could also contact Avatar and have them build one for you to your specs. That and their Hellatone speaker are a great (rebranded) buy. Dave there is super great to work with. They made me a Traditional 212, black w gold piping, closed back, with a G12H30 and a Classic Lead 80. I think it was less than $400 and shipped in 2 weeks. That was years ago, don't know the current rates. Great to deal with. Splawn does custom cabs too for $525 'ish I think still.
Ask those Craigslist guys what speakers are in those cabs and what ohms they are and go from there.
