Rear diff seal is done. Vinyl is gone and seats are in for custom replacement.
New 1992 C-150 owner. Only current mods are a 6" lift kit installed by the previous owner. Needed maintenance: rear diff seal, oil pan gasket, exhaust leak and questionable freeze plug. Planned upgrades: Remove vinyl rustomatic material on cab exterior and coat with Line-X Extra color match, Full body paint; Line-X bed to third row foot well; second row 60/40 bench replacement; custom upholstery. 351 to Stroker conversion, twin turbos seem like a natural fix to the exhaust leak.
