Do you offer an adapter to allow Carter W-1s to be mounted to a 1409 intake?
There are no two hole to two hole carb adapters in the Offenhauser catalog. I can find no evidence that we ever manufactured one. Usually hot rodders were going for larger carbs and we have many two hole to three and four hole adapters. I would look for a local shop that could either cut one out of billet or print one on a 3d printer. it shouldn’t be too hard to engineer one.
