I believe it is. My 4346 is for 69 427/425 or 396/375, and the vacuum takeoffs are as you described. (Except for the dashpot, I don't know what that is) I have one on the front of the baseplate, at a 45 degree angle that goes to the vacuum secondary.
Point is that your 3246 sounds like my 4346--and it makes sense, since the applications are identical.
I know that in 69,the 4346(396/375) and the 4053 (301/290)only differed by the metering vent. 4346-yes, 4053-no. Therefore you can be relatively sure you can use 3246 for 69 302/290.
Long way to go to justify that last statement!!
