Looks like that's probably the route I'll go. Did you have to do anything to the Blazer lines?

to get the blazer line to work you have to run a 2 inch adapter from the line to the drier or change the drier to one where the line would connect on the front instead of the side of the drier.

I just finished my ac system/ serpentine setup. I used parts for a 94 chevy truck ac compressor, powersteering pump , water pump , alternator, clutch fan assembly. then used the main line to compressor from a 88 s10 blazer , the small metal line off of a 84 cutless and condensor from a cutless since the lines are on the passenger side. then used my drier and evaporator from my el camino.

You should never reuse a drier once it's been opened up...
