Ok, after a short break to welcome my new daughter I was able to put a little time in on the 47. Had a pretty productive weekend. With the chassis mocked up at ride height and leveled I was finally able to get started. The blocks and shims put the lower arm level. Plus if I go any lower the engine hoist won't fit under the control arms.
I didn't get a good picture but I took the rear tires off and set the rear end on the ground. I also blocked up the rear of the frame so it started at the same height with the weight of the cab.
