Had to use the smaller scissor jack to fit where I needed it to go. Also had to put a couple blocks under it to get to the right height. I was able to jack her up and block it one more time by myself with no issues.

Then I added a block to both sides in the back.  Again, needed the scissor jack to get it where I needed it to go.  I ended up getting a second scissor jack, thinking I might need one on the front and one on the back when I finally bolt it to the body.

I am within a few inches of where I need to be to mount it. Not sure if I will block it one more time or just jack her up the rest of the way. I may do some measuring of the bolts to see how much wiggle room I have.  I will double-check with a rod if I am still lined up to where I need to mount it to.
