...that explains a lot... 
(I remember calling for a quote for a replacement 3rd gear (the bearing had failed underneath it), I remember it was Sid at Ferrari Houston told me the good news was that it was available for $1300, but I'd have to buy the whole set...Found a good used gear for $250, but also bought my brother's 1970 Mustang 351C convertible thinking that getting a 4 speed into it would cost about the same as that single Ferrari gear...).
(even further off track)--The most expensive table I remember seeing was one a friend Kenny had in college, Kenny was a wrench at a bay area porsche shop in the 70's (and again in Phoenix nearly in his 70s...)--each leg was a Porsche 911 crankshaft). Somehow, there is nothing on a Mangusta that belongs inside the house...ok, 'cept the Ferraro steering wheel...)
