The diagram on my advance unit (single) is shot and needs to be replaced. Does anyone know of a replacement that looks original? I've checked out a few online and they don't look anything like the original design.  Thanks...

You will need to find a NOS unit or have it rebuilt

You have two options

1 - mechanically advance it as much as you
     can, then put in a b.b. to plug up
    the vacuum and it looks stock

2 - contact Jim Woods to have it rebuilt

Best of luck !

I second the Jim Woods statement, fantastic person and knowledgeable.

Sorry to disappoint my supporters (thanks guys!!) but I can't do the single advance units; only the dual ones.  I know Brian McDevitt does these single ones and I don't know who else.

There are generic aftermarket units that look identical to the originals.  I guess you would call them NORS?  The Autolite logo on the originals is on the back side under where it mounts and almost impossible to view when installed, so the NORS ones are a good option.  There are some on eBay.  Expect to pay $100 - $200 for one I think - and take a close look at how the plating looks before purchasing.  Search for DD-190, which is the ID number.

Here are some others that maybe still rebuilding them.

JC just sent this to me

This one is on Ebay

This is a used original but rebuilt vacuum advance, used on the cobra jet cars (hp6) rebuilt too factory specs, both sides hold vacuum and ready to be used.

Possibly you can contact this individual and ask if they rebuild them.  Then you could reuse yours

Best of luck on your journey
