Anyone know how to obtain a build sheet on my 89 YJ? Looking for some details as to what equipment was in it at time of production. When I purchased it 3 yrs ago, it was pretty much stock, although I believe some mods were made such as the gears and possibly the fuel tank. As far as I have read, the 89 YJ's only had 15.1 gallon fuel tanks?? I was showing little less than a 1/4 tank and filled up, it took 15.4 gallons??? Any insight???
