The Steelcraft rockers we were provided don’t fit as nicely as the Heritage ones (which are still acceptable, but getting worse as the tooling wears out) so some extra adjustments were needed when fitting these to the car. We carefully fit and adjusted both rockers to match up with the doors and fenders.
Once everything fit nicely we rustproofed the front of the membranes and the inside of the rockers before welding in place. The rockers were spot-welded where possible and plug-welded everywhere else.
