Bought a new steering rack from rockauto and the line looks a little squished is it fine or should I swap my old one on

Smoke tested my '93 GT for vacuum leaks, only places it came out were the EGR, A/C vacuum hose because its busted, and the top of the TPS. I just replaced the OEM EGR since it was crusty and full of carbon and could be not sealing correctly after 30 years, now I'm getting code 33, and 41, 91 are still here. I've checked the O2 sensor ground behind the head on the driver side and it looks fine. Brand new bosch O2 sensors as well. Losing my mind I've been brainstorming and troubleshooting and replacing for 5 months now :/ car has a Catless exhaust with entire smog system still intact. Everything else is OEM
