I do agree. I cut my old rubber off of mine and could not believe how much corrosion ran all the way though them.
I did upgrade my 90 amp alternator at the same time from 90amp up to 136amp. Mine is supposed to have a 150A. This Jeep is charging so nice now.
I need to replace my damn headlights though. He put aftermarket one piece units in. They are horrible look terrible and won't asjust. I need a good factory set up put back on and hope he didn't alter anything when he installed them. Unless these aftermarket ones don't require doing any altering.
