When I purchased the car, I noticed that the exhaust covers were dented right next to the jacking area.
The original jacking area on the car was a small steel bar that was bent into a loop shape and welded to the frame. It appeared that the underside of the steel bar was flush with the underside of the exhaust. Therefore when the car was jacked-up the jack pad would contact the exhaust cover and dent it. So I decided to fix this.
My solution was to fabricate aluminum mounting pads that were 1/2" thick and mount them to the frame. By using this thickness the underside of the jacking pad and the exhaust cover are no longer flush with each other. I can now safely jack the car up without touching the exhaust cover.
Before I installed the new aluminum jacking plates to the frame, I removed the original bar loops. I then drilled holes in the frame and installed riv nuts so I could attach them with a machine screw.
Below are pics of the aluminum plates. The rear jacking pad is larger than the front jacking pad. I used stainless steel bolts with allen wrench heads. I counter sunk the mounting holes so the bolts would be flush.
