Having had to install heat and AC using junk yard parts before the good stuff became available, I will have to say that a package from Vintage Air, or one of the other manufacturers, is the only way to go. For appearance and fit, it is very hard to beat the package of quality components these folks put together. If appearance and properly mactch components is important too you, or if you value your time at more than a nickel and hour, it's by far the best deal. Just my 2 cents worth.
