Go to Summit or Jegs and get the Edelbrock pn8723 kit.It has the spacer,studs,and gaskets that you'll need.For future reference,the base gaskets for the AFB,and most other square bore carbs[Holley,Edelbrock,ect.] are interchangeable.

3499 or any 400HP carb did not have spacers but.....ones for the 327s will not work as the secondaries are larger on the 400HP carbs and with the smaller spacers the secondaries will not open completely.

These newer spacers are big enough to handle as big as an 850 cfm Holley,so your little 3499[about 600 cfm] will not have any issues here.The Edelbrock pn 8723 is a wooden spacer which is a better insolator than the phenolic [plastic] spacers,and has the better 4 hole ,as opposed to the common "open" designed spacers out there.
