I bought an FD with this particular kit installed and the heim joints are shot on all of the links (trailing and toe). Does anybody know the size and thread pitch of these ends, so that I can get replacements? Thanks!

Remove and measure them or just contact Petitt. I never had problems contacting Cam.

 

not pettit but when it came time to refresh the rod ends in my rotary extreme parts, I used FK rod ends.

I used the FK rod ends as-well for my trailing arms and toe links. Make sure to get the dust covers too.
Here is a good post from back in the day with some sizes and part numbers.

5/8" x 18 thread. Also make sure to get two left-handed threaded rod ends for the trailing arms.

 

Thanks all. Will remove and put a caliper on them soon. Yes! Going with FK 3 piece. Easy to source and the standard bearers it seems.
