With the first GMC install. I made up an extra mounting kit/hose kit. My hatch is hinged. It opens to almost vertical. Glove box is usable. 2.4 hours to mount/hose holes of the Vintage A/C, and heat. 45 minutes for the A/C hoes. Mounting kit has drilled holes in it to mount relays, and other Vintage Air electrical components. Vintage A/C can be pivoted down with out removing any bolts in floor. Also made a part that makes the entry door close much nicer. Was a good day in the Mouse House. Bob Dunahugh 78 Royale + 4 COPO Yenkos
