134a Conversion Question

[tvhj]

My '92 A/C has bit the dust and since I'm about out of r12 I'm converting to 134a. Plans are to replace everything in the system, new R4 comp., all hoses, etc. with the exception of the evaporator as I'm afraid the dash will crumble into pieces. Most parts are coming from RockAuto. After searching all the related posts here, I have not found a good part number for a drop in parallel flow condenser. Does anyone have a good brand and part number that they have used? Also not really sure which orifice tube and pressure switch to use. Thanks for any help, really want to get it right the first time.
