Wondering if anyone has the dimensions or compatible ball joints for the front knuckles? Working on using the FD spindles with fabricated arms on a project and know the oe are not replaceable.

 

I started down this road until I gave up and ordered the Moonface LCAs and Nagisa UCAs from RHDjapan. I believe their ball joints are replaceable, but you might need to research that.

What specific dimensions are you looking for? I have an extra arm sitting around that I can take measurements from.

 

I have arms as well was just being lazy since my searches didn't give me much. Need to measure the thread, taper at both ends, as well as the large taper stand off to control arm bushing center lines.

 

Upper is an M16 pinch bolt ball joint. Height from shoulder 33mm.

Lower is an M14 thread, small dia 16.19mm- lg dia 18.19mm height 21.3mm, Looks like a moog ES3009R may work for this. May buy one on the way home to check.

Still working on/need help on finding the pinch bolt setup for the front.

 

Mazda uses the pinch bolt style on every FWD car and the FC. 626...

 

Looks like the ES3009R works but its a tie rod.

Checked the 626 and few others at the store but all were 18mm stud pinch bolts instead of 16mm.
