To justify sneaking away like that, fbp, we had just come out of an evening of -40F and it had warmed up to -10F but was snowing heavily in a blizzard so we felt pretty good leaving here. I thought I would have to leave the car at the end of the driveway and walk in dragging the suitcases when we got back, but a neighbour had come over and plowed the driveway and yard out and then it started to melt in a Chinook and it's still melting.
Back to real life; car building, with the drivers front wheel lowered and put back together, I remeasured the height. It is 2 1/2" lower now and it feels more springy when I bounce on it. I noticed that when I put both springs into their hats, they both caught on the edge of their hats and were 3/4" higher than they should have been. I pried them over a bit and 'Sprang' they popped into place and felt good. My point is maybe this happens a lot with Mustang II front suspension and it could throw off our measuring. Anyhow, I'm quite a bit happier about my height now.
The second picture is a mediocre one of the height before the suspension change, and I don't think the motor is touching the frame at all.
