I found out today from the folks at Scott Drake that the coil bracket is made for manifold mount, not on the front of the head as on a Windsor. But, if you cut the slotted hole on the adjustable/slide straight out it will work. And with the cut out slot (looks like a u shape, not a slotted hole) under the dipstick tube, you can't see were it was cut. So it worked.
You really don't know what the whole story is behind repro parts. Trail and error is exspensive
