All good suggestions - thanks.

Need to go rooting around the chassis first to see what's going on before I start fabing something up.

You mention chassis flex. I read on this forum that someone had the running board aprons hit the cab with some chassis flex, and he was using the shackles, not a hard mount on a stock frame (my repro aprons were close and I spent an afternoon clearancing them to the cab when I was doing bodywork) Makes me wonder if I hard mount them if it won't crinkle some sheet metal.
