Here are some pictures of Jack's new parts car. The first one shows me using the Come-Along to pull the car onto the trailer. Note the use of car dollies under the rear wheels.
The Come-Along only had a 6' length of pull, so once it was drawn up we had to reposition/shorten the yellow strap to pull it another 6', and repeat, and repeat, etc.

Unloading it went about the same way, except once those dollies were on the garage floor I had Jack start it up and use the front brakes to ease it off the trailer. The car is at my parent's house, which is a 3-car unit my Dad built using recycled timbers from a barn he tore down across the street. With an 8"x10" overhead beam, I've used that Come-Along to remove several engines in the past. Just need to move some of my Mom's clutter to get the car positioned to remove the engine.
Jack is anxious to get started. The plan is to have the swap completed and running before schools starts up at the end of August.
