What you've got will work, but custom length ones are cheaper to make, lighter and arguably (is that a word) stronger. I have a bush one end like yours and a heim on the other. Just replaced heim after only 8 months service. Heim looks ok but has a sloppy ball

, looks like the teflon lining has dissappeared. I might try and put a rubber sleeve on each side of heim to keep teflon lining in and crap out.
Well... its a simalar subject.

If you break it... build it stronger.
