Aris, does the new NOS distributor and the new gear you have ordered have the 13 tooth count? Not 14 teeth.

Another advantage of a NOS unit over one merely sent out to be setup on a SUN machine (assuming it was originally done right at the factory), is the fresh shaft & bushing.  The improved performance compared to one with worn parts is VERY noticeable.

Thanks a million KULTULZ! Am on it this week to determine timing and other parameters however, to make a decision decide first I have to take delivery of the NOS as mentioned.

'The photo with "shim?" with arrow is not where shims are installed, if anywhere. That "collar" is to be tightly held in place with a roll pin. The collar should be pinned to allow a minimum of .020" up and down thrust of the shaft. My 1955 book calls for .020 to .024" thrust. The correct position of the gear is also a critical dimension that must be followed.'

There is your answer for the correct driven gear placement.

If one has a DIST that needs the driven gear relocated, the normal practice is (was) to locate the collar/gear and re-drill the shaft ninety degrees off and insert new pins.

If you have a NOS DIST, all of the adjustments should be correct out of the box. 

Be mindful that the actual DIST ASSY CASTING NO on the bowl is an ID NO and not a SERVICE PN. The SERVICE PN(s) you find in the CHASSIS CATALOG(S) may be superseded PN's and may cause confusion.

The correct vacuum signal from the carb has to be determined first before trying to change the DIST SETTINGS.

If after installing the NOS DIST you bought, if she rattles on acceleration get back as FORD had a fix for that.

Any questions at all just ask and someone will help you with them.

Still waiting for glamour shots of the car ...

Ted, I can in no way imagine you as being 'bad'.

It finally dawned on me 'shimming' was meant to located the driven gear correctly on the shaft.

  My bad on the comment about the shims as that was a memory hiccup on my part.  I was originally referring to shims in the vacuum can and not the end play for the lower gear.  0.022-0.030” is the 1957 specification for the distributor end play so it should be similar for the earlier model distributors.

The dual diaphragm L-O-M distributors and the 1957 and up distributor vacuum pots did have some adjustability at the vacuum chambers by using different shims, springs, and spacers.  Looking through my stash of early single diaphragm L-O-M distributors, they all have non-adjustable vacuum pots.

The photo with "shim?" with arrow is not where shims are installed, if anywhere. That "collar" is to be tightly held in place with a roll pin. The collar should be pinned to allow a minimum of .020" up and down thrust of the shaft. My 1955 book calls for .020 to .024" thrust. The correct position of the gear is also a critical dimension that must be followed.         Trying to precisely  adjust the advance springs while in the engine will be challenging. Standard vacuum gauges are not accurate enough to split an inch of vacuum/mercury into a fraction but  by experimentation you may get the  "feel" of it.  The vacuum advance canister will need to be disconnected from the carburetor and then plumbed to the pump and gauge because with no load on the engine, the air flow through the carb will not provide a good and proper signal. There are devices available that can be plumbed in for precisely measuring small vacuum signals. If you would like to see the one I have, I'll gladly try sending a pic of it.    As stated above, the NOS distributor you have may be calibrated well enough out of the box.  You could push a vacuum hose against the canister connection and with the other end clinched in your teeth, make sure everything moves freely.

Yes KULTUZ, that is why I bought a NOS from eBay yesterday, hoping it comes pre-adjusted. It is PN FAE-12127-A as shown on the picture , my spare one minus the gear I ordered is FAE-12127 A2 and the one on the car must be the same. My parts manual has three PN's, FAE 12127-C (which I wrote must be for the Police Merc of those days as I found also a Police Teapot version), a FDC 12127-A and a FEC-12127-A
So all numbers are the same, so I believe and hope all will fit.

This is my spare Loadomatic without gear but I have ordered one.
On the shaft I measure 0.058'' play, if this is the place to shim, what should the tolerance be
?
