Points change question

Hi All
I just bought a set of new points for my straight 6. 280se
Can anyone give me some tips on turning the engine over to get the high lob in the right position in the distributor. i am having difficulty with access. I can't seem to get a wrench or socket on the fly wheel to manually crank the motor. What size and type of wrench should i use?
Thanks.
John.

The engine will turn much easier with the sparking plugs removed, and one can even turn the engine round by applying pressure to the serpentine belt and using the fan blade ( with on non visco fan)

Much appreciated.

I just bump the starter until it lines up. I have a remote starter switch that makes the job real easy

bump the starter a few time , also if you are almost there rotate the rotor clockwise to align . invest in a meter made for cars , it will have a dwell reading so you can use that to set point gap [ cheap ] ebay .if you see something there , send me the item number so i can see if it is ok .

points are easier to adjust dwell. with engine cranking and dwell meter hooked up adjust. this is as close to running adjustment as posible is way more accurate than point gap. if you really want to set point gap get close with stater then losen distributor and move it to highest opening on points. then put back close to where it was the adjust timing with light and your done. useing dwell method you wont need a timing light anymore after first setting dont move the distributor and as points wear adjust dwell back to same as you set and timing will go back to the same as you set it

Don't forget a tiny bit of distributor grease at the place where the points ride on the distributor-cam. Don't want those new points wearing down prematurely.

Happy Motoring, Mark

Only issue with an aftermarket ignition conversion is the ready availibility of parts if one of the electronic bits should fail suddenly.
Point problems can often be resolved (at least enough to get you home)
by cleaning or adjustment. Otherwise, it's a simple matter to carry a spare set in the car.

Happy Motoring, Mark

My thoughts too initially but the Pertronix units have worked troublefree year after year in Six of my cars.
The instant starts smooth idling and maintainace free running add up.
