Vehicle: 1987 S10 Blazer, 2.5L, 4 speed

Been trying to get this thing off for 3 days. Got it off the block easy, but can't for the life of me get in to a position where I can unbolt it from the exhaust. I've removed the drivers side wheel well and tire, which gives me direct access, but there's trans/vacuum/fuel lines all in the way. Has anyone ever done this and how did you go about doing it? My 30-day expires in 3 weeks and my other car isn't a snow car, so I need to get this thing replaced so I can smog it, thank you!
