they only post the ones that have had revisions/changes. The missing ones apparently don't have revisions.
The nice thing is that they are in color. I printed them all out and sub out from the originals.
I also print out a single sided copy. I have the single sided ones in the shop and the original plans in the house.
It is nice to be able to look at two pages at a time. When a page is completed, I cut the top right corner off so I can easily see if there is a page with something I have not done.
cheers
