My 98 Yukon is running now -- purrs like a proverbial "kitten" and I'm happy as a proverbial "pig in s*#@" -- for now, let's hope it keeps on. So far no leaks or codes.
Thanks to
Suburban-97 for the helpful thread.
One thing that could be emphasized is to hand crank the engine to TDC before removing the distributor.
I didn't pay enough attention to mark the distributor and rotor position. So, I ended up having to time the distributor. And, that meant that I had to reposition the oil pump shaft. I couldn't feel the shaft with my very large long screw driver and "assumed" it was too big.
So, I carefully put a bit adabter and screw driver bit on a long 1/4" extension. I turned it some, but still couldn't seat the distributor. On my second try, the extension came back missing the adapter and bit.

Everything seems fine now. But, I do have a small nut and a smaller nut left over.
