For Beach-Burban,

Your underdash setup could very well be a dealer installed item as every photo in this thread seems different. I did considerable research on my unit and while it does not appear on the build sheet (still inside on the glovebox lid) I believe mine was installed at the dealer. Guess they used factory a/c parts when doing the install. Anyway, the engine bay looks factory. Had mine converted to R143 when I replaced the new compressor 5 years ago. Otherwise cools efficiently. I am still looking for an owner's manual for the Harrison Unit.
