Does the gen IV fit in a FSJ ,answer yes like it was made for the fsj,Image

Biggest challenge for me at least was ac lines and heater hosesImage


Image

Of course there are other issues to consider,defrost ducts,dash vents,type of controls to be used,firewall wall mounting,condenser,drier,hoses and lines, compressor, etc

Thanks for starting this thread! Once I start installing mine, I'll post up here as well.

Quick question - I see that the unit mounts to the firewall, was there a strap or mount from the top to the inside dash?

Here’s a picture of gen IV and bracketsImage
Image
First view is looking at unit from back side (toward dash) blower on the right,ac ducts left,defrost ducts center left.

Next view is parts that come with universal evap,note the brackets (lower right) large bracket mounts unit to firewall,smaller bracket to dash.

Additional parts needed inside cab will be defrost duct (defrost ducts supplied are not long enough), must use Vintage Air controls to operate unit 79 era can use 3 knob/lever (must use some kind of plate over oem heater controls) or 86-91 oem head can be modified with cable converters.

Easy way for AC vents is to buy the underdash vent system from VA (can be painted to match dash), in my truck we used small aluminum vents and made a plenum to conect duct hoses, if I had the chance to do it again would have welded extension to bottom of dash for larger ac vents.

Last is lines and hoses which is the tough part,your going to have to patch holes in firewall by welding them up or bolting in metal plates, aluminum 4 port bulkheads look cool on a clean firewall but are a real challenge because of limited space to make 90 degree turns from heater out/inlets to bulkhead,ac lines can go out oem hole in firewall.

universal condenser and drier with trinary switch, also used 2 port bulkhead, but can still run the hoses thru the original opening top left of drier

Note: oem style drier doesn't have switch port,the trinary switch is low/hi pressure compressor cut off switch and electric fan switch very useful if using electric radiator fan to provide input to fan controller or to run aux condenser fan with relay

Keep 'em coming! Excellent work. Did you make the hoses and pipes yourself?

Great glad it worked out, saves a lot of time not fabricating mounting brackets, please post a picture of dryer and tube when you get them installed, I am interested in the length's of tube from condenser to drier, Cheers

This was our install, at least the pics I took of it, and the very cool dash that Page Customs customized for me.
