bought a new set of 50# injectors from a member on here from a 12' camaro. he said they would work and they look like they will. im in the middle of the changeover and ran into something. the o-rings are the same sizes and the distance between the o-rings are the same. but you can see the part that goes into the intake just after the o-ring on the OLD injector is longer. will the new injector that is shorter work just fine? i dont see how it will matter but just want to confirm before i put this back together. there must be a reason for it being longer or shorter....
