Yes Ken, Nice job!
As far as using newer GM 16" outers with old GM 16" centers. They don't fit. The centers are too small. I ended up cutting the outsides off the old 16s leaving the riveted section on the center. Then we turned it down to fit the new outer. They came out fine but I really didn't like the look so I gave them away. Here' a picture. The fronts are 15s. The
rears are the ones I made. Also Cokers don't loke dirt roads. Beater
