Bolting Shaker to Carbs

[Mopar_Mudder]

On a 426 Hemi their are cross bars on the base plate that goes over the top of the carbs. Is their a nut on these that hold the base plate to the carbs before you put the air cleaner lid on?

The carbs have studs that thread in. The carb base plate goes over them and are screwed down by wing nuts.
 
Good reproduction or OEM base plates should work fine.

Keep in mind that there are 2 versions for the Hemi intakes. They have 2 different spacings. OEM & Marine air cleaner base plates.

Shakerhood.com has both of these available. Roseville too perhaps. Hoovers Auto Parts has the right Studs and  correct wing nuts also.

The base plates also had "feet" spot welded onto the valve covers if the car had a Shaker.

Hard to explain but I am asking if their are two sets of wing nuts that go on the studs. A first set the holds the base plate to the carbs and a second set that holds the air cleaner lid on, clear as mud right......

I would guess that their are two sets or the cross bars on the base plate that the stud goes through really don't serve a purpose.

Yes, 2 studs and 2 wing nuts.
Here's mine.

[Topcat]

only use 2 wing nuts. Not 4. Studs thread into carb.

Then can some one tell me the purpose of the cross bar that goes over the top of the carb?
 Highlighted in my attached picture.

I would guess to keep the shaker in position as tight as possible , so the shaker cannot move on the carb neck

As explained, need 2 studs, one on each carb.  Then the baseplate goes over the studs in the center of the crossbars.  Place the air filter on the baseplate, then the lid, then the wing nuts secures everything.

I just thought it looked like their should be something that bolted down the cross bar,their is enough room between my lid and cross bar for a nut, so really it does nothing. The lid does not contact the cross bar when it is tightened down either, well I guess it could if I did a little reshaping on the lid. Maybe that is the intent, the lid is suppose to tighten down to the cross bars and mine doesn't hit.

Do you plan on using an air filter between the base (item you posted with crossbars) and the lid?  If not, you will need to do some reshaping.  The air filter is oval in shape, just a bit smaller that the lid.  Here is a photo of a non shaker so you can see the base, air cleaner, lid, then wing nuts.  Its similar to Shaker setup.  The shaker scoop covers the lid.  But you will need more parts like adapter ring that goes around the base etc.

Yes I am using a stock air cleaner and have all the parts. Just trying to figure out the proper assembly. My base is made for the newer Edlebrock carbs so the cross bars have been removed, I am not going to go through the hassle of making them fit if they don't actually do something. But since they were their is seems like they must have a purpouse or else all that is holding the shaker on is the lid of the air cleaner that is pressing on the filter element.

I see now.  The crossbars help to center the base over the carbs quicker and it does help to secure it.  But it will work just fine without the crossbars.  Once you tighten Takes a few more seconds to place the base over the carbs and assemble as if you did have the crossbars.  The wing nuts will keep it secure.

I ended up making the cross bars fit. Had to machine a little off from the top of the carb choke towers and add a spacer between the cross bar and base plate. Now when I tighten the wing nuts down is draws the cover down and tightens it against the top of the cross bars.

Now I just got to get these stupid feet figured out. I think they built them wrong, the nut is on the out side instead of the inside of the L bracket.

[Mopar_Mudder]

Wanted to post some more pictures of the feet now that I have them on (yes my original brackets were built wrong). Seems like it is hard to find pictures of the feet so I wanted to post some up.

Just a discaimer. These are all repop parts and I had no orginal to look at. So it is as close as I can figure it is suppose to be based on info I could find.

Here is what I used to determine where to put the feet.
