I apologize if this has been asked already, but I searched the forum and could not find any help. My vac adv canister is pointing directly at the back of the drivers side head making it impossible to adjust without moving the distributor. I've heard that you can move the distributor over one notch and move all the plug wires accordingly but wanted some advice before making this move. Thank you in advance...

Here's a pic...

You can do exactly that. Mark where number one plug is like on the block, rotate dist so next plug is there, move wires, then set your ign timing and lock it down. (Maybe check your ign timing first if you don't know what it is).

yup. In theory, wherever the rotor is pointing now with the car shut off, you can spin the dist however you want and just be sure it's pointing at the same wire. Redoing ignition timing at the end is because you'll never get it dead on by eye.

...or you can pull the distributor out and turn it to whereever you want it to be the re-insert it. Leave the cap and wires where they were. Turn the entire thing as a unit. You will need to rotate the oil pump shaft in the same direction (using a long slotted screwdriver). It's likely that your problem is because at last R&R the opposite occurred.

rotate the distributor shaft one tooth counter clock and you should not have to change the wires unless they wont reach. Just reset timing. With the distributor shaft and body moved as one, the points or pic-up orientation with the distributor body will remain near the same. And the rotor to cap will probably be more in-phase with distributor correctly positioned.
