I bought a set of LS1 injectors for a good price to install on my LT1. Anyone using these in an LT1? The clip that holds the injector to the fuel rail wont work, I installed them without the clip but they slide up and down a considerable amount.

If I push them all the way into the manifold the top oring is half way out of the fuel rail.

I put some nylon washers on the bottom of the injector between the Oring and main body to limit the amout they can move.

Has anyone else run into this problem and how was it solved?
