67 1 year only- 68-69 are both c8oz #s rh and lh Then all 69 b9s and starting around april 1 when 69 b2s came out and the F-60-15 XHD suspension shelby option started these 69 b2s and all shelbys built after april 1 or so used the new bigger wider F-60-15 tires and they used a unique 69 b9 strut rod that was never serviced by ford that i have ever found anyway. This unique strut rod was the c8oz type that had a wider metal hump by front strut rod bolt hole that made it stronger for the new big f-60-15 tires. Then in 70-71 ford used this same beefed up strut rod with wider metal by front bolt hole but stopped using the extra added castle nut and cotter pin in the end tip (that was more of a safety thing and served no real purpose). So all 70 and up cars used the new c9zz strut rods after that on assembly line.
