Ok so big thanks to lostFinn for turning me onto the webosto instructions for our chassis. they are in German and there are some differences but it was good guidance. Heater went in about the only spot i figured it could. just gotta move the fuse box which isn't as bad as it sounds as there is alot of extra wire that puts it in front of the battery.
The mods to the battery tray aren't quite as they are in the instructions. (euro instructions and may be for RHD vehicle and the abs pump may not be in the same spot) the abs pump/brake lines are in the way and that plastic is BRITTLE AS HELL. be forewarned. i broke a 2 of the 3 ears on the fuse box bracket wrestling the box into place. i have the right half and 1 tab holding mine but if you kept the tab on the right side and then the one towards the battery and then notched everything else out of the way of abs you could probably have the 2 tabs.
Here is the bracket i ended up with cause it was the material i had. its 16 gauge stainless which is just rigid enough. i would have rather done 3/32 aluminum but this will work. this bracket is different than the one pictured in the instructions as my jeep didnt have the bracket that the lower tab of the bracket in the instructions connected to. Easy enough to notch it and pinch it in the lower battery tray bolt. I will have a more detailed drawing of the bracket in the near future.
Fuse box relocated and heater mounted.
In there and heater lines run. waiting on fuel and wiring tomorrow. Got a late start and i was smoking a pork butt so kinda distracted. worked out for the better cause it melted all the ice out of it today so it wont rain on me tomorrow. Amazing how much ice builds up under there... Oh and the orange is Heat sleeve. since all the flow goes thru there on the way to the heater core i wanted to insulate it at least a tad. the same orange heat sleeve is on the exhaust pipe that exits in front of the sway bar. I dont have a muffler for it at this point and am not sure if i will spend the money on one.
