I think that I have read just about everything that has been posted here at 3rdgen about replacing a bad heater core. I guess that I just need a play by play. James C wrote...Ten-minute job to remove and replace all four screws. The whole core replacement was probably an hour and a half or so. I guess that I am missing the point ... it has taken me 2 days and I haven't even found the right screws ... I would think thatafter this much time I should just hire someone to do this ... I am a hardhead and believe that if anyone can do this operation that I should be able to figure it out ... I suppose that I could peel the dash back like an onion but I know that there is someone out there that can talk me through this ... Thanks in advance Mr.B
