Thoughts on Gen 5 Vintage Air Install

Then, when installing the evaporator under the dash, the stud helps to guide the evaporator into position by inserting the stud through the correct hole in the firewall plate. Later, that stud gets removed, and it's replaced with a bolt that threads in from the engine compartment side.

The other two studs are for attaching the center vent to the dash.

Thank you so much!!
