Vintage air sure fit 64-66 installation need help!

[Raceaprilia]

On the way to keep truck cold in 2014
It did not start that well - ordered one month ago and brown truck delivered the sure fit package for 64-66 today. I started installation right away to make up the time.

Need some help.
1.When I deleted all firewall holes I did not planned to put in AC. This system uses one of the holes and I need to drill. If somebody can provide me with all 4 dimensions on picture that would save my day. Need also diameter of hole.
2. Vintage air drawing to drill firewall is off?? Bracket measure 7 30/32 between holes, drawing measure 7 21/32???
3. See two different mounting of lines - which go where? Picture of only lines make only sense to mount it but it is not aligned right. When test fit they do not fit in the firewall opening? They are way off when test bolted on!! For price they charge I would expected they match perfect.


Thanks!
