[Image: A07_F2_B81_908_B_467_C_A64_C_15_AE5484_A40_D.jpg]

Hello Forum......my (friggin`amazing awesomely fantastical) 429cj was at pre-summer service recently. All was A-ok.......except the vacuum advance on the distributor. It needs to be replaced.

Could someone point me in the direction towards a high quality part. I have have surfed a lot, but I am unable to make a final decision on the part.

I think it needs to be `single port and adjustable`..........

I just dont want to buy the wrong part......

Thanks.

I will not be into town for a few days but will check with the parts house that I got the 351 C thermostats from and see if they have NOS on the shelf. The parts house closed like 25 years ago and they are selling the NOS inventory now.
There was a kit from Ford back when new to eliminate the vacuum advance and be centrifugal. I put one of the kits on my 73 351 C Q code when new. You left the vacuum motor there you just cut the arm off of it. You adjusted the advance by using different strength springs that came in the kit. It was also dual points. It required changing the cam or center shaft in the distributor and the plate and points but was in kit.
I am sure you would never find one, lol.

Awesome. That would be great. Please get back to me if you find something. Otherwise, there is an interesting Crane on Ebay.
It comes with small springs and an adjuster........would it fit?

Ok got by the closed up parts house this afternoon. Good news is they have them but there are 7 different ones listed. Need number off of the distributor to get the correct one. The parts book grouped all of the 429 engines together, T-bird, Torino, Mustang etc. I am betting it is the D1AF-NA. Here are the ones listed in the parts book and this is not a Ford parts book NAPA store if I remember right.
C8AF-AD
C8VF-C
C9AF-Y
DOAF-Z
DOOF-Y
D1AF-NA
C8VF-A
Let me know what the number is and I can get a price.
The NA change at the end means that went through the alphabet 13 times for engineering changes. They started with A went through the alphabet then went to two letters. AA, AB, etc. to get to NA. That would be 312 Engineering changes am I seeing that correct? If Ford did like other numbers they left off the I and l so they would not be seen as numbers.
Thanks,
David

This page should help. looks like it depends on if he has the C6 or 4 speed car.

Edit...
Looked back at an old thread. It is a 4 speed car so it should be the dual point distributor making it the D0OF I believe.

Once I hear back I will find out how much they are and brand. If any other BB guys wants one I can get if you want.
I got a 351 C water pump the other day might check on the 429 and see if they have. I will also check casting # I know nobody will want unless 71.

Wow....awesome. Yes...it is a 4sp car. The mentioned website is an absolute treasure trove of technical information for 429´ers. Amazing site. Who runs it? I have tried quite a few times to contact the fellow over a period of near,y 2 yeats now.

The advance unit on the website doesnt look anything like the unit on my car now. Maybe the original has been changed at some point.

I am VERY interested in purchasing a correct vacuum advance for my car. 1971 429cj ram air 4sp. Please get in touch. Thanks

I am 10000km away from the car now, and cant check the distributor..........can you gleen anything from the initial picture? Definitely Autolite cap.....

I would personally wait until you can get a look at the numbers on your distributor. It is hard to tell from your pic and comparing to the 429 site, but the casting on your distributor looks different, so you may not have the original correct distributor.

I will get you a price tomorrow. If you do want it I will take a vacuum pump with me and check that it is good before purchase. If you want two would make sense to ship both. I can do Export papers as gift I believe and no duties. I have sent to Africa several times.
They are not going anywhere so no hurry very few know about this place and lots of rare parts there.
Cheers,

David
