Welcome to the world of car that could, would and did. Nice back story. A few folks I met last summer went the compact sports car route after hearing my stories of the low slung, mucho nimble Honda Prelude. Right now there are probably a dozen laid off construction workers out in the barn somewhere in middle Va tinkering with their cheap hot rod, while their(former addiction) big ole trucks trucks sit outside these days.
The 2nd gen was supposedly the best one for pure fun. I know guys with Porches, Vettes and other big muscle cars that say they still regret parting with their 85-87 models.
Now at this forum there isn't much activity in the 2nd gen section. Frankly most of us are ignorant of how they work. But a fellow named Jamie had one new. He races his 4th gen and is a very helpful chap while here.
Car-parts.com will be a good place to start. Also your junkyard...used parts across the planet!
If you are near Va Beach there are a plethora of them all the way to Williamsburg. If you don't mind travelling a couple hours, Richmond has some good ones. Even Charlottesville has a few.
Now, go to their websites, fill out a wishlist request for the 2nd gen years. They'll email you when one arrives. I see about 1 per year in Richmond.
Go to roadkillcustoms.com and look up junkyards. Not all the 'big ones' are listed. But there are a bunch of small town type that cater to those old crumudgens at that site. So that'll expand your options. Plus it's a cool site.
Check out this old honda.com as well. Great source for old, old Hondas all the way back to chain drive models. (Yep they began as a motorcycle with a cab)
Honda parts now.com still has
some new stuff. But they list discontinued part numbers and typing a part # in the search bar populates a list of cars they were used on. Also check their acura site using search feature.
I'm probably forgetting something...
