Bill truck uses a timing belt remove the upper cover and loeer cover after that you will see the Cam gear it has letters on it it should be at 12 o'clock with the letter A stamped on the Cam gear. On the crank there will be a notch in the gear that should line up with a mark on the bottom aluminium plate it to should be at 6o clock then the disttributor should line up with number 1 on the dist cap hope this helps
