Thanks 3B. That's good advice smile I was thinking that as well, (replacing the rubber flex lines). I might as well just do the whole job new. I'll check with NAPA tomorrow about the pre-made brake lines. I'm thinking I'll just order the new master cylinder while I'm at it. I don't know about the wheel cylinders yet until I get to that point. Well, actually I had planned on replacing the wheel cylinders on the new rear differential before installation anyway.

Now, it seems the HVAC system is operating okay. Should I bother diving into that? I was thinking about just replacing all of the lines leading to the HVAC and from the HVAC, but not tear into the HVAC itself.......Thanks!
