Working forward the measurements at the center of the bows are :
20 1/2" from front edge of trim to middle of Bow #4 (~22 1/2" from upper edge of drip rail to center of Bow #4 if trim is off)
15 1/2" Middle of Bow #4 to middle of Bow #3
17 1/4" Middle of Bow #3 to middle of Bow #2
16 5/8" Middle of Bow #2 to back edge of Header
These probably vary slightly, they were taken from my '68 with the jigs in place for spacing, but on my top the alignment hole on the jig does not line up with the hole in the side rail for some reason. The Bow #4 dimension is correct, all top vendors I looked at use the 20 1/2". Bows 2 and 3 are based on the jig, the header kinda "floats" as there are no references I've seen...
You can just use tape to hold the bows in place while you install the side pads.
