Cheers for the compliment, yes the box seems to be coming together well.

As for the UIM/LIM: you'll also need the SVT throttle cable and SVT cable bracket for the throttle and cruise control cables. It would be a good idea to get the gaskets for the UIM/LIM connection, the EGR and IAC gaskets and some seals for the fuel injectors.

There's a how to on the main CEG page under mods for removing the UIM/LIM. Take a good long read of it before you start anything.
