I am building the Mack R with the round fuel tanks as well. The air tank mounts seem to be in the way. I made the mistake of gluing the air tank first and had to cut it off to fit the fuel tank on . I would like to see photos of how you do the mounts. Thanks
Great job. I am working on the same Mack. I hope it comes out as nice as yours. Could you post a photo of the airlines and how they go between the tanks and the rear wheels? That would be a big help to me.
