OMG its tight under here?????

[aany001]

Just tried mocking up my Vintage air gen 1 (cable operated) case assembly under the dash in my 69 camaro with a DSE firewall plate and the stacked 4 pass through bulk head and its gonna be a disaster to plump under there!!!!!!!!!! Anyone shed some light here? Also what do I do for the existing mounting hole that they want u to use that is now gone? Also what hole do I use on furthest bracket on pass side on the fresh air cover? I had to move the whole unit about 3 inches to the drivers side just to make room for the lines. Help Help!!
