I'll post this in the part out section since maybe someone doing a total part-out can help me.

While changing the oil on my Evo this weekend I happened to notice the nut was missing off the bolt that clamps the lower control arm balljoint into the knuckle on the front right. And the bolt had worked 1/2 inch out. Very lucky it didn't come all the way out at the wrong time.

So I need the flanged bolt and matching flanged nut as shown below. I'll gladly pay a fair amount as I am having no luck finding this thing. Mitsuparts.net shows not in stock.

 

I found a source for the parts thanks to one of the folks on here, thanks!

 

I know this is far later,but where did you find it? and how did your bolt look? flat spots?

 

I ended up just getting the bolt and nut from the Mitsu dealer in Nashville. No flat spots, but the threads were a bit messed up where it was working it's way out since the nut was missing.
