This will not work if you have an original tail pitch slider with a 5mm ball
The plastic bushing in this control arm takes a 4.75mm ball. One option is to also buy an HN7079A, which has the correct ball. The other option is to exchange the 5mm ball for a 4.75 mm ball on your original slider.
According to Align's website, that ball has 3mm x 3.5mm threads. H60224 contains 4 of the correct size balls.
