So just to finish off this issue, it you use the TR6 bushings, you will need to find spacers for the upper arm that has an outer diameter of 1 1/4 inch and an inner diameter of 1/2 inch and a thickness of 50 thous or just slightly less so that you capture the entire bushing and will still fit through the gap in the frame.
Regular washers will be too thick. Conversely, you can take 1010 thous off of the bushings and use regular washers. Your choice
Hope this helps out members in the future
