I too bought the right side but I think the left will be a better fit. I will be ordering the left side next time. My buddy Bob, who is a machinist made them for me. He had some plastic material that was just too thin so used a fender washer for extra thickness. He kept using a micrometer to get the exact thickness.
Your picture makes me think that the lead is a bit stretched, which because being the machinist he is made the spacer a bit different then yours. Mine fits perfectly and works great.
I had been dealing with the drivers front going intermittent [I could tell because I could feel the pulsation from the right front]. When I removed it the lead was frayed and "looked" worn out.
Going to order 2 more for the 'vert!
