***UPDATE***
Just spoke to RockAuto. Even though I'm over the 30 day return policy (didn't have all the parts due to slow shipping on Honda's part), they will issue a return label and ship out a new part. The guy said that it sounded like something happened in the warehouse or the manufacturer. Honestly, it seemed like this one was a mistake. When I opened it, the nuts were not in their own bag, and the link bag had already been opened.

Hello All,

So, I just switched back to stock suspension from the T1R Basic Damper kit.

I ordered most of the suspension from RockAuto and the rest of the springs and stuff from Honda.

I have two problems:

1) The suspension calls for two different nuts:
51609-SAA-003 = NUT, HEX. (12MM) above the bearing
90215-SAA-000 = NUT, HEX. (12MM) top of the shock inside engine bay
As far as I can tell, the two nuts are 19mm and 17mm outer diameter. I put both 90215-SAA-000 on one shock and 51609-SAA-003 on the other shock by mistake. Do you think that is a problem? Or, should I just fix it now while I still have the spring compressor?

2) I ordered Moog sway bar end links:
K750258 - Front Right
K750259 - Front Left
The front left (K750259) fits perfectly. The front right is about 1mm to big diameter for the hole in the suspension and the sway bar. Do you think they gave me the wrong part? Would it be safe to bore the holes out on the suspension and the sway bar to make this part fit? Literally, I put it in the hole and the threads won't fit.

Please help. Trying to sort this all out today.

By the way, I used the KYB Excel G shocks and struts.
