Hi Laurie, I thought to look in the H 36 maintenance manual 🙄 and on page 19 (Electricals), it does confirm ignition switch spec is MS 35058-22….
And Mike, Tom says that he put a BNR O ring in a test container of Dot 3 fluid for several years and there was no signs of deterioration softening or swelling so indeed it seems they are not so incompatible. He installed the EPDM O rings as the first and cheapest step of a process of chasing down persistent brake leaks. The Diamond-supplied Nitrile O rings that he removed look fine, and it turns out 2 new Pistons were the $olution. Cheers Kristin Sent from my Windows 10 phone
