Can someone post the correct part numbers for python OE replacement injectors for a 91 Sentra SE-R? I'm getting conflicting numbers from a local shop and want to be sure.

They gave me 630-123 and 630-123a.

Also the beck/arnley ones are like $8 more each. I wonder if I should spend a little extra or what?

Guess I found my own answer.

Python Injection guys tell me its 630-123.
