Looking for some help w/ the stock Mangusta ignition switch. I'd like to replace an ugly generic replacement on #1010 with something as close to original as possible.....especially regarding the quality of the key. Imo the current group of reproduction switches - Mr. Fiat, etc - fall short here, so at least initially searching for a period Fiat item is my preferred approach, even if it turns out to be an imperfect match.
The attached image shows the desired type switch from a 1970 'survivor' Goose. I assume it's a SIPEA unit; maybe originally a FIAT 600 part. The perplexing part is the key's rounded shape. I thought the 'standard' OEM key was more of a polygon (shown in pic #2). Can anyone with an original key confirm or illustrate what the top of the key looks like? Maybe there were more than one style used? Is 'FIAT' evident on the original key, or perhaps 'SIPEA'?
By looking at old photos it's clear that a lot of original switches have been replaced with various alternatives. (I've seen smoked ignition terminals on more than one wiring harness so contact resistance may have been an issue). The classic Bosch switch seem to be the most common replacement. Thanks for any help, regards, Nate
