Jmardy, there are only 2 tags on the engine, but 3 unique IDs--standard tags were the carburetor and then the engine ID on the intake manifold. These are available as repro. The key ID is the Detomaso stamp on the intake. The block  on '1076 was stamped with the machining date, of course all the castings have date codes and it seems that the first week in July 1968 is pretty common (but nobody can say exclusive) for the J-codes that went into Mangustas.

Mike, the Veglia tach will work as long as you are taking the tach signal from the  coil. Otherwise, for about $25 you can buy "tach amplifiers" that take a pure +12v or digital signal and basically include their own coil to burst up to something the tach will hear. (Wish I'd known this when I put the electromotive ignition on my 308...)

The bell housing spacer is just that flat disc between the engine and the ZF, and likely the first thing that gets touch from below...But cheap and simple at this moment to replace.

https://pantera.infopop.cc/topic/wiring-gearbox is of course the best information on the ZF safety wiring...(where else but here? ). My guy replaced the differential carrier bearings , its a great time just to replace 50 year old seals--esp, between the shifter box and the ZF case, the dust boot at the shift box, whatever.

Lee, thanks for the link on safety wiring the ring bolts.  Seems like a task I can handle.  He did mention torquing the bolts, but not the torque #'s...   Does anyone have them?   I'm guessing gaskets are readily available, so might as well replace them too...
