no idiots here,there is no stupid questions. 1st to verify you are on #1 tdc (this is the same on every engine) pop off the valve cover and remove the spark plug.watch the valves on #1 cylinder as you roll the motor over in the running direction. watch the intake open and close and verify that compression is building by placing your finger or compression gauge on #1 (this eliminates being 180 degrees out)(like every reality car show on tv)continue rolling until the tdc marker lines up with the fixed index...tada... tdc!! now look down at the drive is the drive slot 90 degrees to the crank?? is the larger of the half moon towards the flywheel end of the motor? if yes the #1 mark on the dist body should line up with the rotor which should line up with the #1 tower/wire on the cap. if not your drive is out of phase and it must be reindexed until it does.

if re-indexing is required first remove the fuel pump,pushrod and stand. there is a tool(i have one somewhere) to grab the drive and remove it but most times if the case is clean in the bore i have used flat tip circlip pliers (like you used on the crank circlip)to grab the drive in the slot and twist it out. Be careful!!! there are 2 thrust washers under the drive to avoid case wear,dont drop these into the motor!if they come out with the drive clean them and slide them down a pushrod or screwdriver into the lower register in the case,some guys use sticky grease to hold em on the drive when reassembling.if they are still in place you can fish them out with some bent wire or just line them up with a screwstick or pushrod ,centered for drive re-insertion.you will have to guess a bit on how much the helical gear will change the index as you install the drive,but if everything is clean it should goes easy as you can feel the drive contact the gear.larger of the half moon towards the flywheel.

A couple of things to add... If you look at the picture of the distributor drive installed, you will note it is offset. This means it is only possible to install the distributor fully down in one position only. This is why the distributor drive must be pulled out and re-indexed if the rotor is pointing the wrong way. One other method to remove the drive is a powerful magnet. Don and I use one of those on Claire's bus when the drive had to be moved by one tooth... And don't drop those shim washers into the engine. You won't like that...

yeah,the magnet on a stick can be inserted in to the fuel pump opening to catch the shims depending on your luck that day
