348 transmission help!

Okay, a while back I bought a part on ebay that was represented as a Michelotto casting for a 348 tranny to add an oil cooler. It was represented to fit later model 348 trannys. Mine's an early model, but what the heck, I bought it anyway. True enough, it didn't fit mine. Later, I asked a local Ferrari tech about it. He said "it's just a 355 part". So, I put it in storage. Fast forward a few years, and suddenly a light came on. I've got a '93 now too, and it'll have a late model trans. I looked and lo and behold, the 348C has a tranny cooler grafted on in exactly the same place that this casting has one built in! Whatamigonnado? I guess I'll sell the darn thing. The pics show the tranny cooler fittings adapted to the 93 348, the housing on my 89 348 (note the extra bolt near the cv boot versus the one on the 93) and the Michelotto casting with the built-in ports. I must have too much time on my hands.
