Thanks for the reply. Yes the part number on the paper in the part bags matches that number. These were purchased from the catalog sales place in Ocala Fl. (Not sure about posting names) They were obviously bought from GM dealers and just repackaged then sold to me, which is fine. The measurements of the bushings are as follows: Measuring from the flat to the top of the curve = 2 1/4 inch, the width = 1 3/8 inch. The brackets that were on the car are: from the flat to the top of the curve = 1 11/16, the width = 1 11/16. So they could squash to get to 1 11/16 I guess, but the width is so different I have to wonder which is wrong? So I was hoping someone had a known GM set they could measure.
Trying to remember why I left sunny south Florida.....
