What center link is this from?

“Better” is kind of a strong word, the ‘73-76 center link changes the direction of the taper on the pitman and idler arms and the inner tie rod ends, that can improve the clearance to some headers.

What steering box do you have? Power? manual? If it’s power do you know the sector size?

Prior to ‘73 thr power and manual steering boxes both used the small sector size. 73+ power steering boxes had a larger sector, manual stayed the same. So, if you have a small sector power steering box and you want to use the ‘73+ center link you need to use a ‘73+ manual pitman arm.

Either way the center link, pitman and idler have to be from the same year range
