where to buy 4 link bar wtih helms on the ends
should have what you need...you'll probably have to buy the tubing and buy the joint(s) and put them together, unless you have them made
if you want somebody to make them for you, SUK (out of Rockwell, NC) does a damn good job
sd.com doesn't carry heim joints. I believe FBI sells them, there is a thread about this very question over on ssm. I'd say go and search for it over there.
actually, you are right. my bad. I actually went to sd.com after I posted that and looked to be sure but forgot to edit my post after I realized I had goofed. hope you'll forgive me
