Hello guys I own a shop and I have been really trying to help out one of my customers , her 89 jeep comanche has major sentimental value to her but the leaky brake master destroyed the fuse box and ive been looking for awhile, the part number from Chrysler is no longer available. So I'm in a situation and i need one asap, so any help would be much appreciated you can pm me or call / text 740-818-1558 thanks so much
