Now this post should get me up to date, this work was done tonight.
Part of the recent rust repair work was to replace both rocker panels. After I repaired the pinchwelds to the factory specs, I realized they would probably end up below ground level! I put the subframes back on and set the car at its ride height (0.00") to check clearance.
After the first round of trimming, which still needs cleaned up, I have about 1/8" under the rockers when the subframe is on the floor. That sounds about right.
I need to tweak the shape in a little better so it's parallel with the ground, I left early tonigh to watch the Pens lose to Detroit :(
