...everything is rusty underneath my '95 9c1. The car was a Pennsylvania rig. Speaking of TSB stuff, it did come with the TSB muffler weight on passenger side exhaust pipe. I was looking at my rear lower control arms and they are a factory-looking black color. They are not rusty like the upper control arms and they look pretty beefy. I wonder if they are from the control arm TSB??? I will still change them out with J&M's though. Maybe somebody will want to buy the TSB factory arms for their sleeper-SS or something...
