Title: 65 Vacuum Advance repro
Post by: Brian Conway on November 18, 2020, 10:45:00 PM
Looks like a good effort being made to reproduce a near impossible part to find ?    Anyone tried one out yet ?        https://www.ebay.com/itm/Ford-Distributor-Vacuum-Advance-Canister-Aftermarket-1965-1967-Fairlane-Mustang/254453601755?fits=Year%3A1965%7CModel%3AMustang&hash=item3b3e9dd5db:g:F~EAAOSwTOdd9Wji

I bought the last one available. It should be delivered Monday. I'll let you know.

Still doesn’t look like you can attach the metal vacuum line by the fitting. Still need a rubber hose

Yes looks like you would need to swap out the outer tip section that threads into the housing. Might affect the settings a little

There is no swapping out. It appears to be all one piece.The discription in the auction confirms as much. The end does not come off. You may be able to machine off the nipple so that you can drill and tap for the line fitting.

Well looks 100% better than the current products.  About attaching the metal vac line: I was thinking a female compression fitting at the vac advance snout.

if not removable then there is no way to calibrate it like the originals. i would not waste my $$.

I was wondering about it was meant to be calibrated too. They are not supposed to be one calibration fits all without a lot of compromise.

That's exactly right.

Most aftermarket default to a one-for-all design. Nothing new, we are all aware of this. The compromise would be a need to run the base timing at "other than factory" settings. It is plausible to do such but I agree that an adjustable advance (similar to an adjustable auto transmission modulator) would be far more desirable.

We can let Jim tell it how it works out. Maybe, just maybe it is adjustable.

In the past it didn't matter if they were adjustable or even worked just that they looked good. We would disconnect or cut the diaphragm arm inside,plug the nipple before putting the hose back on .That was because many of us would gut the insides of the distributor and put in a centrifugal advance and duel points for better seat of the pants acceleration . We also plugged the the thermactor ports and gutted the smog pump to make it free wheeling.  Everything looked like it was assemblyline but with added performance.

another thought but not mentioned in ad.....possible to be adjusted by using allen wrench in nipple fitting as some aftermarket ones do.

Pretty sure you could add the detail to the end to replicate the fitting the originals had but still have to figure out how to attach the steel line .   If your concerned about showing the car the point deduction may be the same between wrong advance and lack of steel vacuum line

Jeff, the end is made as all one piece with the body.The part with the nipple does not detach like original. As I said in reply #4 you may be successful with milling the nipple end down flat and then drill out and tap for the metal tube fitting.

Yes I saw and read reply #4 was more focusing on the sides of what I think your referring to as the nipple end that is suppose to look like a male fitting screwed into the main housing and attaching the steel vacuum line to the housing. It would have been a 6 sided fitting where the one in the ad appears to be circular or have a round base instead. In this way the center of that area could be drilled and a metal tube inserted and sealed as another option/possibility

Just choices and different paths to try and get this looking closer to the end goal

So even dead originals with screw in lines are worth something?

In a scenario like I mentioned in reply #10 where the advance is converted to being centrifugal only and not vacuum activated then yes. You can have it replated and it can look the part of being functional and no will know that it isn't functional. I am not sure how it could be successfully used otherwise.

Yes, I understand.
I'll have to see about getting these plated for those who need to have the correct appearance.

for what its worth I was able to replate a NOS unit that had a good diaphragm last summer with a brush plate system..

It looks like it came out better then I would have expected for a brush system.
