Yes Keith,
SMS Auto Fabrics.
I've been referring fellow 300 owners to them ever since you put me on to them back in 2000. Finally able to utilize their services myself. I was leary about sending my current panels to them for refinishing due to cross border shipping and possible loss, etc., thus I wanted to find an additional set.
One footnote Bob regarding the front panel metal frames - if you use a 68 you will likely need to drill a new hole for the lock knob as they were farther to the rear on a 68 vis a vis 69-72.
