Hi all. I've completed the alt. conversion on my Vitesse, and just wanted to share a bit of learning. I used the Rimmer-supplied kit, which is billed as suitable for all sports 6 cars. All went well in the main, but I had an issue with the spacer they supplied (part no. 147472). This spacer is 1cm too short for the Vitesse (and probably the GT6 too), preventing the alt from aligning with the crank and water pump. The correct spacer is part no. 147483 (which is 1cm longer).
After discussion, Rimmers sent me the correct spacer, and all is now well.
Disappointingly, they charged me for it (!), when in fact the error was theirs. Only £3 or so, but a bit naff on their part IMHO.
Anyways, please note the need for a different spacer for the Vitesse (& likely the GT6).
Cheers
