Hey guys. I have unbolted my exhaust one too many times and i have a feeling it's going to strip soon so I wanted to get new bolts and springs as an added precaution. The bolt and spring I'm talking about are the ones that attach the DP to the stock 02 housing. I was looking at mitsubishiparts and i THINK these are the following part numbers, looking if someone can verify.

MR431025 - bolt
MR431024 - spring

THANKS!!
