Finally got some time in this week. Doing the tear down solo sucks however. Getting the box off was the only easy part.
I also learned from the Impala build. Unless you are cutting them with a torch, pull the front springs before pulling the motor and cab.
The bow in the old springs seems to match up with the 200,000 miles on the odometer.
After a couple sketchy hours I had the cab off.
Trust me, pull the front clip separate. Major pain in the rear. Have the cab mobile for now. I'm going to pull the harness out of it sometime this week.
