I bought a very weird wagon that has a custom intake on it using a pair of Solex 34PDSIT carbs.

I've rebuilt the carbs and definitely have them synced up, had a buddy who is a god when it comes to multiple carb set ups help me out, and It still runs like absolute dog crap because of the terribly made intake.

At this point I just want to swap back to the original intake and put a weber on it, but have no clue which intake to look for. I swear I saw somewhere on here that the dual carb intake is wider than the single carb intake, but cant find it for the life of me. Any help on this would be greatly appreciated.

Thank you in advance

Pretty sure there’s a current post on FB showing the DC intake equal in length to the single carb which make sense. There’s no difference in the block or heads so no reason to stretch the intake. 
 

Guessing you have a narrow case EA71 from 1979 and earlier. Beginning 1980 they get a wider case. Intake might still be the same, I’m failing to recall. 

Oh that's probably what I was thinking of then. It's a 78 so it has the narrower case. if anyone has a narrow case and a wide case intake and could measure the width you would be a life saver. Dont wanna source the wrong one if possible haha.
