just recently got my own CCSB in need of a restortion picked her up for 800$
I considered that when I replaced both tanks on my 85. It’s near impossible though with the exhaust coming out of the rear. Didn’t want the exhaust too close to the tank and diesel exhaust needs to come out of the rear because of soot. Even with a rear exit the back of the truck builds up with soot very quickly.You should replace the rear tank with a Bronco tank for extra capacity. I had all the parts ready to do it when I sold my '95.
