Ok think I found it in the Fitech drawing and forwarded it to my father. This is just a simple throttle body injection system where it basically acts like a carb but more efficient atomization of the fuel. No fancy timing controls or anything but am stuck with the old distributor carried over from the 2.8 to the 3.4 unless there is some obvious reason to move on from that should be good assuming we hook it up right.

My father is performing the 2.8 to 3.4 swap and looking to add a FiTech EFI Go 3003 Throttle Body Injection. He has a modified intake manifold that takes a standard Chevy 4 barrel. Fires up good but finding 2000 rpm idle. Gets a little bit better 1200 rpm when disconnect vacuum advance on original distributor. Was wondering what is the ideal vacuum reference on that with original emission equipment eliminated. Looks like a standard Chevy HEI but wondering what adjustments need to be made to run it like this or should just pick up a new one. Vacuum measuring 17 inch from the Fitech going to validate that with a gauge. Verified fuel pressure is correct and having it recalibrate the idle air controller controller did not do anything. After I verify is hooked up right and and all readings make sense will be off to the Fitech Forum. 1986 Jeep Commanche

Checked with my father and he has a dana 44. Should be adequate as long as he doesn't do extreme offroading. He uses it as a plow truck and to move engine parts around while looking cool and likes the really long bed. Dana 44 should hold up to even an LS as long as he doesn't offroad it. Found this one here. https://www.tsmmfg.net/jeep-cherokee-comanche-dana-44-complete-rear-disc-brake-kit-2562-44.html And saw some forum posts about modifying explorer stuff. Looks like custom rotors no matter what you do but my father does work at an aircraft grade machine shop although he does not have a lot of free time. Forum post mentioned the TSM setup above uses GM pads and calipers so would be nice to identify replacements. i think replacing the whole axel might be overkill but am open to options. That wilword setup above looks really nice. Also is a premium for the ebrakes with the TSM so wondering if you guys suggest a driveline brake. Thanks for the input on the Dual diaphragm booster. i know the firewall is different on the 86 vs all the other years so maybe need some pics from my father. If anyone can confirm fit on an 86 as well as a part number that would be nice. Thanks for the help.

Been pouring over forums for brake upgrade options should my father decide to put in more power for his 86. Finding lots of dead links and no longer available stuff. For upgrading the the fronts looks like woodward sells a kit although also need to upgrade to 16 inch wheels. Was also wondering if anybody went with disks on the rear. Both the front and rear stock brakes have a bad habit of rusting up and getting stuck at least in Connecticut. I am not against drum brakes but these are not particularly good ones. Also wondering if swapping the master cylinder is recommended with any of the suggested changes. He currently has a 2" lift and looking to probably upgrade to bigger wheels anyway. As always thank you for your time and if I missed a good post outlining options for this year feel free to let me know.

Thanks, going with the crutchfield one as already getting speakers/stereo from there anyway. Will see which way my father goes with his engine choice after he gets it moving again after getting it painted. He will either fix the oil leaks on his 2.8, swap with a 3.4, go chevy small block, or LS. I know that with early 86 nothing is straight fordward other than the 3.4. I will probably reach my 10 posts in no time if he tries to stuff a V8 in there.

Antenna base is stripped and looking for a replacement. This is an early 86 Comanche with a 2.8 V6. Original or aftermarket does not matter if fits and looks ok. Photos of the hole attached. Found one claming to fit on ebay but looks like it is for a flat surface. Finding an antenna looks easy enough but the base not so much.
