2wd 1977 Blazer LS swap, mild drop….escalating

[Advanced Design]

While I should have stayed with the factory ac system, I do like the clean look you can have with Vintage Air so we ordered the sure fit system. They make a great product, though I didn’t like the look of the plate that goes over the existing holes.

To avoid using the plate, I filled the holes with 19 gauge by butt weld and metal finishing the shrink as best as possible. It probably would have been cleaner to replace the firewall on that side and maybe less work.

I still need to drill for the ac and heater connections, fill small bolt holes and support the evap case under the dash by welding elevator bolts to the firewall.

Yeah, I should have stayed with the perfectly good factory system.
