USDA says beans should be pressure canned, but lots of people have been doing things against USDA guidelines for generations with no ill effects. Not for me to judge, but I do pressure can them.
BTW, dilly beans are great! If you've never had them before, they are worth making a batch, but you probably don't want that many.
A couple of thoughts. Freezing them and then trying to can will not turn out well. Nor will freezing them without blanching. They will last a long time in the fridge, and that's what I'd do if you can't get canner parts right away.
What parts are you waiting for? Most "farm stores" (FarmKing, Rural King, Fleet Farm) carry canner parts that may work. Usually Presto brand that are near universal. Should have gaskets, pressure gauges, safety valves, etc sitting on the shelves.
