Denis, sharp eyes, I hadn't noticed the rear markers were missing...I guess it was fate then to end up in Europe 
The car had been topcoated at some time, there were traces of paint on the windshield gasket. But even the door jambs seemed original paint and all the chassis looked only old, no sign of repair. I seem to remember they still had the bellhousing ears and idler pulley with bracket-- but no jackshaft and no headlight lever. The AC, original manifold (#201), distributor, smog pump, original fuel lines, handbrake lever, water valve, heater, choke riser tube, tool bag etc were in boxes mixed up with some other car. Almost for sure, the other pieces were somehow in the house where the 'crazy Eddie' (the guy there in the same neighborhood who had built the fake wall so it could not be seen with the garage door open...). But as some estates and some families work, the pair in Emeryville were able to negotiate getting the 2 cars but received no help from the family, and you can bet that the jackshaft landed up in a recycle bin somewhere...
But miles of original undercoating, oil pan, valve covers, and inspection marks everywhere. As rust-free as a 50 year old Mangusta could be, with really no fabrication needed for the body (save the trunk floor I think, lord knows why these seem to disappear on Mangustas). The interior rear view mirror came up for sale on Ebay after the car was on sale at Gullwing. I mention this only because I had enough willpower Not to buy a spare (!). But that mirror is still on my mystery list (I cannot identify where that mirror may have been used on any other car).
I said the price was a bargain, since around that time a few project cars came up for sale and $125k seemed to be the floor for a car that had rust, minimum 8 boxes of parts removed and wouldn't run...But when if the result is to be a $250k car, suddenly 1000 hours of work are needed and well, you better really want to do it... This car will end up a good one, I'm lucky the pair selling the car were kind enough to let me just take pictures of it...Lee
