A/C Hose Template

[lkt1954]

Here is a template I created to run the a/c line through the front of the fresh air box. I used a vintage air template and changed the actual hole sizes.
The dark grey is the hole size and the light grey is the overall grommet size.
I don't want a bulk head, so the hole diameters are larger than the lines to accommodate feeding the lines through with the fittings crimped on them. This template is 2.75" longer than the vintage air template.
My question is do I have 8" of vertical room to do this in the fresh air box?

Thanks
Larry
