I've used them in the past but only on 1600 engines, so your question made me curious. Seems Bus Depot sells a Pertonix system that fits all buses and Jbugs sells a compufire that does the same. I'd say call your favorite vendor and confirm. If you go this route, keep your points and condenser in your travel parts bin in case the electronic system fails (they don't fail slowly and will leave you stranded).
