This is probably a stupid question, but how the heck do I mount the vacuum advance on the distributor?? heres a picture of the vacuum advance I have. I've looked at the shop manual and flipped through Denny's pictures, and still couldn't figure it out. I bought the engine without a advance on it, so I never got to see how it should be.

Thats exactly what I did, but nothing happens when I put vacuum to the unit. The arm can't be shoved into the advance at all. When I have the unit off the distributor, I can push the plunger in, but it pushes the clamp away from the advance, which than doesn't line up with the hole on the advance.

From whom did you get the advance unit and what is the part number?

I got the advance from classic parts:
http://www.classicparts.com/1947-62-Vacuum-Advance-6-Cylinder/productinfo/83-274/

The clamp doesn't come with it, but I found one in a pile of parts that was with the truck.

It looks to me that the unit you received is not the unit in the catalog.

Call Classic Parts and tell them you received the wrong part. If that does not work, ask to speak with a technical support person and ask him/her if you may send to them a photo of the unit you received and a photo of the unit you tried to buy.

Would someone else reading these posts look at both photos and give their opinion?

I think your onto something. The '54 manual shows the curved collar like I have:
http://chevy.oldcarmanualproject.com/shop/1954truck/54ctsm0619.html

But, this thread says that the '54 manual shows the car, not truck vacuum advance

So I have a new truck vacuum advance, but the collar from a car 235.

The back surface of the "vacuum pot" is not flat on your unit. The back surface of the original pot and the back of the unit in the Classic Parts photo is not the same as on your unit. I have bought two units from Classic Parts and they look like the photo in your catalog, not like the unit your received. I think they sent you the wrong unit.

The collar from a car is different from the collar from a truck but either one will work with the right unit (as long as you bend the vacuum line).

It looks like the clamp collar might interfere with the hold-down bolt on the octane selector. Maybe a clamp from a truck and a vacuum unit for a car? The entire units can be switched (with re-positioning the vacuum tube), but can the collars be switched?
