AC Heater Unit - Part 2

The heater unit fitting needed to continue before the body could go on but there wasnt a great deal I could do on this. 

First I cut two holes in the stainless inside the area where the heater was going, one on each side of the tunnel. This was so that I could add footwell vents purchased from T7 designs. These just clip into place after cutting the right size hole (about 74mm).

Next was to drill holes for the water and a/c hoses to fit through. This is a slow and steady job, first use a 3mm carbide drill bit at slow speed with cutting fluid and after this you can open the hole fairly easily 2mm at a time with normal drill bits. Dont forget to use rubber grommets to protect the tubes.

A drain hole was also required to pass the drain tube through, but other than that all the edges were sealed with sikaflex to meet the IVA requirement that no air can be taken from the engine bay (note there is a caveat that drain holes are ok as long as they are less than 1% of the overall space used to take in air).

Following riveting the panel in place and adding a p-clip for the drain hose the stainless protective sheet was removed from the engine bay and now the heater will be left alone until after the body is on.
