5. IMO, replace the hoses, especially if using R134a

B. original evap will work
E. newer condensers remove heat better
F. IMO, original system has more value on a "stock-ish" truck. Original system is a good design, will recirculate air or use outside air, aftermarket designs do not. If you want a clean firewall go aftermarket
G. recommend repair shop that offers a warranty on parts & labor. Most reputable shops have at least a 1 year/ 12,000 mile warranty (whichever comes first)
H. replacement evaps are a direct fit
Now that was an education. Thanks a bunch B.W.

F. IMO, original system has more value on a "stock-ish" truck. Original system is a good design, will recirculate air or use outside air, aftermarket designs do not. If you want a clean firewall go aftermarket Agree completely.

G. recommend repair shop that offers a warranty on parts & labor. Most reputable shops have at least a 1 year/ 12,000 mile warranty (whichever comes first). Meaning I should put off the compressor until it's running (ground up restore). Wouldn't normally do that for OEM, but there doesn't to be a shortage on A6 compressors.
