For anyone who may care here, here's a quick photo diary of my install.
After taking a rock to one head light, I replaced both headlights with
He.lla H4 24V 100/90W (HLA-H83140041) bulbs, adapted a
Doorman 9003 socket, with
rubber shell connectors from Erik's, to fit the stock wiring harness, and then a
IPCW CWC-7006 7-inch plain round conversion headlight. I did have to buy longer Philips screws to secure the face of the headlight bucket back down.

I've never had these type of headlights before (the H4s), but, of course, the glass light housing was design perfectly for them, It only goes in one way and firmly keeps the bulb in place.
I sprayed a little bit of silicon on the rubber boot and it slid over the Hella light bub with ease.
As you can see, the glass denotes proper orientation. "TOP"
The only problem I had was that the new glass housing stuck out more than stock, and the stock bucket cover bolts were just too short. I had to replace all 3 bolts on both passenger and driver's side.
I removed about 1/2 of the plastic sheath on the socket cord, added Packard connectors on each wire. I also moved the crimped on wire numbers to the new socket plug.
FYI: I used this thread as a quick pin-out reference for wiring. Just be careful when viewing the pictures. One of the pin-outs is from the socket (plug) perspective, the other is from the H4 light bulb perspective (so they're left/right reversed).

You can also see that these glass bulbs are more flat vs the more round front surface stock ones:
