Hello,
I found out that this car do have serious rust issue on passenger side floor pan... we took out the carpet and center console out, (it was very difficult to remove the center console) you could see SSP item on both floors.
rear quarter panel area is all intact, no rust of any kind. It made me puzzled where the water leak is coming from????
Passenger side seat, bracket is rusted out as you can see in those pictures i just uploaded.
What's your advice on the floor pans?
Unfortunately, no build sheet!
