The new (to me) RV-10 has an IO-540-C4B5 from a piper twin. The current starter ring support has slip rings and slinger holes for electric prop heat and de-ice fluid. It appears extremely heavy and will interfere with planned electronic ignition install. It looks like lightly used or NOS ring gear assemblies (149t) are pretty easy to come by, but I don't know what all of the subtle differences are. Would P/N 72245 work? What about 74329. It looks like that latter has de-ice slinger holes. Any help would be appreciated.
