55.2-59 Vintage air

[PDW HOTRODS]

I have a Vintage air kit on order for my 1957 Chevy truck, but it is at least 3 months out. I would like to know if anyone could help me. I am relocating the battery under the floor and filling all the holes in the firewall that I don't need. The Vintage air instructions show a drawing of the firewall but they don't specify what holes are needed to mount the AC. On the drawing there are holes labeled OEM hole and some with no label. Could anyone tell me what holes are needed? Also does anyone have a picture of the firewall with no battery and AC installed using this kit? I know some route the hoses different way but I am thinking of routing them the way they come in the kit. Thanks.
