My CB antenna was on my ARB front bumper. I'm not a huge CB/radiophile, but I think that you might get a slightly better ground plane if you are near the hood (using one of those hood lip mounts) due to the large surface area of the hood (as opposed to the back bumper and composite bed). The only downside the the front location is that you'll have to look at the antenna when you are driving (which isn't a big deal in my opinion).
90404-51319 - Union
90930-03136 - breather vent
two stainless steel hose clamps
5' of 3/8 fuel line
The current diff breather screws into the top of the rear diff (drivers side of the pumpkin IIRC). Unscrew it, and screw in the union. For the extension, I ran mine to the fuel door. Drill a small hole in the plastic surrounding the filler neck, and attach the breather vent to the fuel line and clamp it. Run the hose down to the union on the diff, and clamp it there. Tie off the hose to keep it clear of things, and make sure there is enough slack in the hose to allow your suspension to droop.
Hey man it's Michael. Thank you for all of the knowledge on the taco last night. I would definitely like to get the part numbers for the diff breather parts. My email is email@example.com. Also I was looking for your post on the parts you have for sale for the taco I havenít been able to navigate to well on the forum to find them.
