We lack bike parts shops up here. There's some in BC and ordering for the states is a no go shipping is wild. If I order I tend to get stuff from Europe because oddly shipping is cheaper than from the US
I failed to mention that I’ve found a few bits and pieces on Amazon. Tried to go to the Fito website and got directed to there…they were the only one with brand specific springer forks! (I just installed these, the faux tank, and the lights….sooo guten nacht, y’all. For work awaits.)
CRAIGSLIST. Example: This old Huffy (?) currently online for $50! I probably wouldn't be able to find a banana seat frame for less let alone a sissy bar.
Or this parts farm. One of many hawking $10-$20 bikes just outside city limits.
I find these deals listed without mention of brands or types so searching keywords doesn't help, often excludes, but scrubbing through the low priced section typically pays off.
