Intake manifold & Carter B&B stud spacing is different? Now what?

[rrunnertexas]

Since the original intake and exhaust manifolds were cracked and leaking on my PJ, I found a nice looking used set of manifolds, cleaned them up and painted, ready for the install.  All bolted up well until it was time to connect the Carter B&B carburetor.

 

The original manifold has a carburetor stud spacing about 3 1/4" and the "new" manifold has a spacing of about 3".   At the moment, there is not a way to bolt the carburetor to the manifold.  

 

Now what?  Is there a different carburetor base plate that will swap out to the smaller stud spacing?  Maybe an adapter plate?

 

Help!

 

Pictures attached.

New manifold.

Open up the holes in the carb base. 1/8 inch per side doesn't seem too drastic. Good luck.

Also note that on the new manifold there is no small holes on the flange for a govenor like on the old flange.  Need to know what car or truck and year the new manifold came from and also to verify that the correct manifold was originally on your engine.  Need to know the part numbers to make sure.

Yes should be an 1/8" vacuum port on left side

Allbiz,

 

I used a die grinder with a carbide bit to open the holes just a bit and the carburetor did bolt back on and seems to run fine, as before, but without exhaust noise.

 

Rich, which small holes for a governor do you mean?

Booger,

 

Yes, that vacuum port is there and working.
