Looking at the witness marks on my actual gas tank, after my drive shaft had pulled my shield down , it looked like it was barely rubbing. But still, I am not feeling that comfortable with it rubbing on the actual gas tank itself. So I want to give it an extra 1/4 to perhaps 1/2 inch clearance.
07JeepXK when you installed your adjustable track bar did you make it longer than the stock one and if so by how much ? Otherwise some day I will have to measure and try that trigonometry stuff. LOl
When mine was rubbing I did have both my front and rear sway bars disconnected.
