RN,
It's me, CREWZIN, on my son's computer in Maryland. Your extra body-moldings that you added to your PT between the wheelwells is hiding the welded reinforced lip that's used to support the jacks. That lip is reinforced and strong enough to be used to jack up the PT at either end about 3-5 inches from the end. Not sure how your bodywork is attached or if it will interfere with the positioning of the jack. You might have to use some other stronger points, front and back for your jack points.
