Hey folks, so good thoughts.........
I had been told about the JBW fix, a friend has done this before with other OEM parts and has not had any issues. The Permatex product is great, it doesn't harden and I've used it on the bolts that need a little sealer and/or locking in place but not a loctite kind of fastening. The original part is NLA (duh, most stuff we need these days seems to have gone down that path). The replacement is for the E21 and if I remember correctly has two threaded ports so one just needs to be plugged and it's a direct fit, but +/- $200.
Tech71, if you have a good used spare message me please. Thanks for the comments folks, I'm off to a work project for about a week then back under the hood. Last milestone was pre-oiling on Tuesday and all is well.
