Deceided to replace my points and I am just waiting for my new points to arrive. While waiting I am trying to find some info on how to go about changing them.
I cannot find and directions on how I go about dismantling the distributor to replace them.

Any help would be appreciated

Hello again
It is fairly straightforward, remove the coil assembly, and condensers from the top of the distributor,(3 screws), when you lift them off DO NOT rock them for and aft to break the gasket free, if you do you are sure to break the carbons on the side of the slip rings, (the carbons may need replacing anyway, and the sliprings may need skimming in a lathe on its own shaft if it is pitted) if the coils are stuck by the gasket, only rock them from side to side until you can lift them away.
if the distributor side plates are still in place (where the HT leads plug in, be very careful with them, they become seized in with time, gentle tapping with a piece of wood may free them, mine were siezed solid, and nothing would move them, I had to resort to very quickly heating the ally case with a welding torch, and tapping them out as quickly as possible, before the heat got to them, (whatever you do don't break them).
You can now get into the points remove the 3 screws and a splitpin and they are out, fit your new ones and set up as per the instuctions for the timing jig.

Regards
Peter Smith

Hi Peter

I read your instuctions and it seems fairly easy to do as I already have the distributor on the bench with the coil and caps removed.
I now just have to wait until the points are delivered.

Once again thanks for replying to my problem.

Easy is like a 60's gm car with a uniset..and a window in the cap to set dwell..these are not easy.

I am not an expert but....obviously unscrew and reattatch new parts..clean up as nec everthing..make certain the points address each other flat and flush when closing..bend if nec...
put mech back in case and adjust point gap on tip of lobe. both sides..double check fool around and recheck a couple times..the hard part (for me) is reaching in that housing and setting em. Now you have to set synch screw..(the mystery screw beneath the side plate base timing setting screw)
put in box and mail to jake flemming in texas!! he will synch and time the unit....d'oh........or
if u get a motors / chiltons manual from 40s/50s. there is a procedure to measure left vs right vs mounting holes and open close time...this is essential. other wise think of a twin engine boat with 2 engines running at diff speeds..your engine has in essence 2 dist systems in one box..operating independantly of one another..dialed in you can do 50+ in 2nd gear....or have a real dog....I bet Mr. Knapp can chime in with some wisdom..most older "sun" machines could do them..and maybe up there they are still around..not here..jake or skip in fla are only 2 guys I know of....
I used 2 timing lights once and adjusted to get single "flash" like a boat engine synchro..kinda fun to play with..I would rather drive than work on this thing anymore...
I implore you to be certain to replace both condensers...I had no luck with nos..Earle Brown has new ones..Skip in punta gorda rebuilds coils all new guts..jake cleans? them...
this dist is about the best most trouble free part on the car..do it once right, and forget it..

Hello Jeff.
From your comments, I take it your not volunteering to do any of these for anyone then.
Seriously, I have already passed on the instuctions for the timing jig, of which Cokekid has 2, he shouldn't have any problem with the job, but expect to spend 1 1/2 to 2 hours setting up and rechecking, and rechecking,till it is spot on.
I don't see a problem, Patience is all that's required.
What do you mean by Jake cleans them, I thought he rewound the coils?
Regards
Peter Smith
