First time around I was pikey, and used a G40 alternator on a CL engine mount - which requires a bit of spacing here and there to fit. Then I used G40 twin v-belts, using the inner race on one pulley, and the outer on the other. Timing pointer needed minimal bendage.
In the end I did it properly, and removed the metal timing pointer, and fitted a CL alternator; pulleys and lower timing belt cover. Yoof and Hayesey have retained the metal timing pointer though, and just bent it up out the way.
