I recently purchased 1987 standard cab 108 inch wheelbase 4x4. I have been surching for a fuel tank that fits. All tanks listed are in the 50 to 51 inch lenghth range. This does not fit my truck as the original is around 44 inches. Does anyone have a solution for this or heard of this. To use the larger available tank requires cutting out a crossmember. Any help on this is appreciated. Thanks
