HVAC
Little out of order as I did the following in pieces over the last several months, but just finishing up the full HVAC install including full compressor and condenser upgrade.
To start, installed the restored heater box and AC evaporator boxes. One key item here was the drain - I did not love the idea is using clamped or glued clear hose, and got a little lucky. I figured out that a completely unrelated part was near perfect and still available (see pics) just trim a tiny bit off the top, and the funnel fits perfectly with both the chassis hole and the evaporator box. Little tricky to line it up and slid the evaporator box down into it, but works great
Aside from being a general PITA, interior job was relatively straightforward forward, noting order of operations is critical. Heater box, Dash top, temperature control probe into ac box, connecting vent on top of ac box, slide that whole thing in, then the heater controls and cables. Getting out of order will be a headache.
Moving into the engine compartment, did the full sanden and parallel condenser upgrade according to the great DIY threads linked below. I used the LC Wylie bracket, coupe king parallel kit with mounting brackets, and fittings/lines from Cold Hose exactly as listed in the DIY. I found it super easy to use the Vevor crimp and make the lines myself, first using clear tubing as recommended. My line lengths were a little different than the DIY thread as I mounted the drier slightly differently, but they were perfect for estimating the order, and I had left over.
Will update this post with a few more pics once fully complete
