Datum line height measurements for 1971 Super Bee needed

[71BEE]

Need the datum line height measurements to the bottom of the frame as I'm building a frame jig to put my 1971 Super Bee on. I have the drawing from the service manual, but it doesn't show the datum line heights. Any help would be appreciated thanks Daryle.

In the past I've contacted Cheif EZ-Liner the frame machine company, there old tram guage measuring system (UMS) has all of the specs. I've always been able to talk them into looking back thru their data and have them email full specs. This is what the body shops would have used to straighten frames and unibodies before the new high tech laser systems. A little bit of math and you can easily get every measurement you will ever need.
