Yeh no problem mate. I pretty good with what other parts will fit your car so if you get stuck on anything at all, just ask. Another quickie aswell if you want to enjoy any interior mods such as a GSi Recaro interior or uprated dash computer etc. Remeber that all Vectras pretty much have the same wiring loom so if you get anything from a high model Vectra, they will fit straight away and just plug in.
The heated recaro seats, fuel computer, dash and a few other bits were all uprated in my Vectra Turbo and made it pretty much exactly like a GSi, but was a turbo instead lol.
