Props on a what appears to be a job well done. Thank you for the writeup and please keep us informed of your impressions as you get to drive it more.
One thing I think might help, that I have not seen mentioned in discussions on this topic, is the trick of placing your bushings in the freezer overnight to shrink them ever-so-slightly to ease installation. I have used that trick on press-fit things like bearings and ball joints with positive results. It seems to me that it should be a similar effect to using heat on the subframe, without the risk of fire.
