Okay, finished it up Friday evening and got it as close as I could.
This works out to a 47.8% - 52.2% front to rear weight bias. Not bad for a 385 series BB.
And here is a picture of how I set/check ride heights.
I machined up a half pin plug and use a machine square level to ensure it's set correctly. Then have some painters tape on the fender lip to make sure I always measure to the same point every time.
Got to drive it yesterday, but my son-in-law was with me so I did not push it to see if it made a difference.
