Fred, there are several builds on this site that show how they did the running board brackets. Check the S10 swap how to post #78 (first link below) and then check post #17 on the second link. The brackets in the 1st link are "homemade" and the ones in the second link are the stock brackets cut down to fit the S10 frame. There are many others but most use the same principle as these two.
