Slowly unpacking and sorting the spare parts. Need to consolidate or thin the herd so I can get the Spider into the garage!
Looks like a good assortment of panels there. You could likely sell off most of what you don't want & use that money towards some replacement headlight glass.
Battery lids $10-$20 each, the dashboard radio-mount insert panel $20-$30, decklids/doors $50-$100 each. The long narrow taillight trim panel with the early "850" emblem is a 1.5-year-only item & getting harder to find in decent shape nowadays, with no rust on the panel & good chrome on an unbroken emblem $75-$100. The fuel tank area cover panel can be found all over eBay & it seems they rarely sell, might just want to hang onto it (the outer ends tend to cave in a bit if some oaf sits on that area of the car). Same goes for the convertible top cover panel - it can (often will) warp if someone sits on it. The center console is a matter of taste & convenience (the front tray is handy), could bring $50-$100+ depending on condition.
If the large rear body panel you have is the 1967-69 type, is in good shape & you want to sell it, I'd be interested in buying it for my early Spider (previous owner backed the car into a parking lot steel post).
I'd also recommend you swap that spare front bumper onto your car - it looks to be in much better condition than what's currently on the car, & good-condition early bumpers are getting harder to find without the seller thinking they can buy a house with the proceeds. You can sell off the worse-condition (rusty) one, with the value of it mostly coming from the under-bumper Carello front turn-signal lamp assemblies (also used on other/higher-end Italian cars of the era). It may be easier to sell the turn lamps separately from the bumper, but those 2 little Phillips-head mounting screws can often be a real b#%ch to remove without the head stripping out & making a REAL mess of things!
Definitely keep the tonneau for your car! They're
very handy when parking the car on the street (or garage) & keeping the interior tidy (& safer), also adds a bit of curbside "period" eye-candy. I had one on my old '69 850 Spider for years & years & loved it.
Hubcaps...assuming you're keeping the steel wheels & they're currently bare, keep the best 4 (or 5) caps & get rid of the rest. In your photo, left column caps #1 & #3 look like keepers (#4 is for a Fiat 128, not 850), right column #1 & #2. Don't expect to get much money from them - lotsa people already have damaged caps. But for the owner who has none at all & doesn't mind dents & scratches, yours would be ideal at a cheap price.
Is a head for 845 motor worth much? Handwritten note attached says "valves are thin":
The value of any 850 head, whether the 843/817 or 903 type, really depends on CONDITION; combustion chamber damage, stripped spark plug hole threads, stripped/damaged/missing studs or stud holes (especially the rocker arm studs), & remaining overall head thickness are all factors.
The valves look normal size & to be seated normally in your photo. The "
valves are thin" note might not talking about the valves themselves, but rather how much "meat" is left on the head; the thickness of metal visible between the bottom of the spark plug hole & the surface (face) of the head can basically tell you the overall thickness of the head, ie: how much has been skimmed off in previous repairs/rebuilds, & how much is left on it to skim off should you need to resurface it again. A severely-skimmed head also affects compression ratios, & raises the possibility of valve-to-piston contact (since the valve heads are now closer to the pistons).
For most folks seriously considering rebuilding an 850 engine that will perform well & last, the more "meat" left on the head (the closer to stock/new condition), the more valuable the head. Due to the angle of your photo, it's very hard for any interested buyer to see this critical area.
Unfortunately, your head looks to have combustion chamber damage in cylinder #1 (on chamber edge at the 9:30 position), cylinder #2 (foreign object multiple contacts on face opposite the spark plug) & cylinder #3 (foreign object multiple contacts on intake valve head & chamber roof between valves, with possible crack between valve seats). Some of this damage
could be remedied by surfacing the head, but that would depend on how much "meat" is available. The perceived damage between the valve seats in #3 might just be carbon deposits & photo angle/lighting, but that damaged intake valve should be replaced (IMHO).
The casting code on the exhaust side of the head, in the center between ports #2 & #3, will tell you what 850 engine type this head came from. You should find something like 100G000, 100GB000, 100GC000 or 100GBC000, along with a 7-digit Fiat casting part number.
