The Forward Control chassis did have the updraft and they were sold to outside companies like Boyer and Grumman who made bread/milk trucks out of them. Step Vans are models 3445, 3545 & 3745 Forward Controls are models 3442, 3542, 3742, 6242 & 6642. To the best of my knowledge they all got the 235 Thriftmaster Special engine, so no 261's during the TF years got the updraft carburators. So, what model is your truck?
