Can anyone give me a link to part to fix this without having to buy a new adjustable control arm for my rear passenger side. The bolt broke clean off and I’m not sure what brand these are.

 

You could try contacting Megan Racing, Hard Race, or any other company that makes that style upper control arm and ask. They are probably all made in the same Chinese factory.
You could also remove the rod end and take measurements and search for one online. Replace the other side too while you are at it.

Though from what I've heard, that failure is not uncommon with that style of upper arm. If you don't need adjustable upper arms then look for a used set of OEM. If you need adjustable upper arms Ikeya Formula and FDF make good replacements.

 

Didn't know Honda built a 4 seater version ?

 

Well, that's kinda scary since I'm running a similar arm. Do you really want to run the same thing again after this one broke?
