I'm having my motor rebuilt now. I just didn't have the time, space or the intestinal fortitude to delve into it at this point. I've rebuilt a couple motors before and do agree it's a very worthwhile experience. Not everyone should jump into it, though. There are many less complicated vehicles to begin a rebuild adventure with. Like a motorcycle!
Regardless, I've spoken with Terry when I was investigating shops and he seems to have a good reputation from what I gathered. There's also Vintage Jag Works in Blackfoot Idaho. I ultimately found someone more local to me and I'm glad I did so I could check up on the work...
