"oh yeah, forgot i had that"

several years i bought some spares from a guy here in-state, i don't remember much about him or the transaction. anyway, the parts i bought were the interior plastics - rear, sides, and roof for my 260. when i met him to pick up the parts he brought along a box of other stuff and asked if i wanted it. i opened the flap of the box, identified it as wiring, and didn't give it much more thought than that. i waffled a bit, and then on general principle said "sure, i'll take it" without really knowing what was there or if i needed it. 

today i remembered that box. and what i received for the price of the plastics included  the engine bay harness, the fusible links, fuse panel (w/ fuses), relay panel (w/ relays), the patch panel, the ignition pack, and part of the dash harness.

I had a similar situation.  A couple years ago, I bought a spare '71 complete engine & transmission on a cart, a spare dash, 2 complete doors, about 10 or so gauges, a bunch of taillights, a spare gas tank, several boxes of parts, some plastic interior, a series 1 AM radio and a complete running and restorable car.

I paid today's going price for the AM radio for everything.  That was just 2 years ago. I doubt I could do that today.

ok, your find trumps mine. sounds llike someone just wanted everything out of their garage.

One of my favorites to this day was from over 10 years ago, I bought a 240z for pretty cheap and as per protocol, it came with quite a few spare parts. Aside from the engine stand, tons of -an fittings and hoses, other fuel pumps, regulators, and general performance stuff, I found a crankshaft with V07 stamped on it, along with a set of Mechart rods. Mind you there weren't any performance connecting rod options then like there are today, so I was pretty stoked. Wish I knew more about them but I don't really ever see them mentioned. I think once in one of the 'how to build your L engine" books.

 

Honorable mention would be a 280z I bought 9 years ago that had a v8 swap, been sitting in storage for 25 years. Upon parting out that one I discovered a scarab bellhousing on the m21 transmission, along with many other little scarab pieces. It also had some custom bubba brackets and axles made for a c3 corvette differential that was installed. Despite the fact that I made quite a bit parting that one out, it still gets me that I bought it with a crack free dash, and thought just simply covering it from the sun would protect it. I should've pulled it out the first day, because in less than a week of texas sun, it split in a couple places. 

if my experience is any indication, that dash would have split if you had parked it on a shady mountainside in west virgnia on a cool spring day. these plastics are becoming my nemesis.
