Recommend an AC system for my 68 Barracuda

Nothing fits like the factory stuff. Nothing. I cannot STAND Vintage Air stuff. The controls are chinsey, the boxes take up GOBS of room and none of the bracketry ever fits just right. I've installed several and they SUCK. Get the factory stuff, convert it to R134A and be happy.
Do you have any more info, or maybe a write-up on how to make factory air work and be dependable? I have factory in my 67 Valiant. I have no idea if it worked, but I'd like to refurbish it if possible versus using a vintage air or other aftermarket unit. Are parts available to service and rebuild it?
