I stumbled across incredible YouTube videos posted by Neil Loughlin showcasing restoration work he's performed on a friend's '63 R2. Some of this stuff is covered in shop manuals and printed articles, but seeing it done with your own eyes makes it a lot easier to comprehend. There are 25 videos of the R2 Neil posted. I've attached links for #1 and #25...the "before" and "after" videos. Check out the other 23 videos. fyi - his YT channel for more tasty stuff - including a 1957 Golden Hawk.
