So I got a rear sway off a Del Sol, and all the hardware to put it on, but...the bolts for the mounting bracket are what I am wondering about. Do the models that come with rear sways have threads into the subframe, or do they bolt through with nuts on the back? I went to put it on and noticed there are no threads, but I told Honda dealer I needed everything to mount them, and they didn't give me any nuts. Anyway thanks.

I don't see a nut for the bolt in this pic, that's another reason I am asking...

 

fyi that pic is for integra's.
anyways there is a nut welded on the back side of the subframe if that was your question.

 

Well, the picture is the one from the Honda parts catalog for the Del Sol vtec model, but ya they're pretty much the same anyway.
