Thanks for the help! I called Vintage....they said no one had any problems installing ,but try turning unit upside down and rotate fittings upoward into place...didn't work.Instructions said to assemble all fittings and brackets including the firewall cover plateand then install into dash. Finally , I removed all fittings firewall cover and front brackets , lifted inti place , then installed all fittings thru the opening in the firewall...a/c line req'd crowfoot wrench use inside car up between unit and firewall. Now to put j-nuts in firewall to mount firewall cover. Back on track again! Thanks!
