Distributor help!

I read in another thread (from Russ) that the B2000 and B2200 heads are interchangeable. What about the distributors? I've got a 2200 in my truck, all ignition parts are new but the dist, and it has an intermittent miss, ususally under load. I've got a parts b2000 motor, but I know that visibly the dists look different, mainly on the mounting tab. Will they interchange? I wish I'd known about the heads before I spent $300 on a new one. Thanks in advance.

the distubutors will interchange as far as mounting, but the electronics and advance curve are different between 2.0 and 2.2. Find a matching dizzy. Distributors do wear out, so be careful with junkyard parts.
