classic air or vintage air?? lets see your pics!

Working on a Classic Auto Air kit on my 74 Duster at this very moment. Nothing but problems. Took them 2 1/2 months to get me a condenser. Everything is bolting on pretty good, but I cant get it to hold vacuum. Got to have a leak somewhere. I think it may be with the long awaited condenser. They are sending me a new liquid line free of charge although it didn't ship for 2 days after they told me it would.
Beginning to wish I never put air on it, because I haven't got to drive it all year. I ordered the kit way back in first of March.
The under dash box really isn't any smaller than the factory heater box. Actually it is a little more cramped because of the extra hookup ducts and controls. And the replacement glove box is a joke.
The cover over the lines coming through the old blower motor hole is neat and clean, but you do have to use self tappers and make new holes.
Good luck with whatever decision you do make.
