I recently picked up an '83 Spectre that's immaculate. It was missing the rear grab bar, but I bought one that should work off ebay.

My first one, that I bought new back in '82 (and that I really regret letting go), already had a really nice sissy bar and luggage rack from the dealer. I'd like to outfit this one similarly.

I doubt I'm going to find anything specific to the bike after 30+ years. Are there any generic aftermarket parts that will fit this bike?
