It's been a long three days trying to get everything fitted into their final spots on the firewall, but the heater and wipers now have their mounting points installed.
I installed rivet nuts for things like mounting the heater to the firewall, mounting the wiper motor, mounting the trans shifter to the tunnel, etc. Instead of buying the $200 tool made to suck down the rivet nuts I just cobbled together a combo of nuts, bolts, washers, and wrenches and sucked 'em down that way. I've never used rivot nuts before. These things are slick and I'll definitely remember them in the future.
It took many trips to the store, eight bags of bolts, rivet nuts, sheetmetal screws, washers, and two different taps. All my pre-fit pieces fit really well. Trying to get the fasteners into all the blind, tight areas turned out to be ONE GIANT P.I.T.A.
The wipers
I made this out of a bunch of the old parts from the original Jeep heater. It mounts over the old passenger side foot fresh air vent. It will be a cable controlled flap that will let me choose variable fresh/recirculation air.
Flap mounted over old foot air outlet. Air will come in through a combination of either opening, travel upwards, then behind the heater housing to the squirel cage fan inlets.
The wiper motor, Air inlet flap, and bottom heater sheetmetal in place.
Everything mounted on the firewall. I'll finish the rest later, while installing the interior of the cab.
