I've recently relocated my battery to the back of the Jeep and I used 3/0 wire for the cables. I routed the wires under the Jeep as we all know how hard 3/0 wire is to bend and fit inside the Jeep. Well, I just drilled a hole in the floor to allow the cable into the cab and I think I should have found a fire wall seal first before drilling. Anyhow, does anyone have any ideas where or what kind of seal I could use for this project to seal the rear end of the Jeep off from the elements? I have some helicopter parts I might use, but I won't be getting them for a few weeks when the plane drops into phase and even then I don't know if they'll work. Anyone have some suggestions? Maybe the guys who did shocks through the floor have anything that you all use?
