Thanks Guys-Appreciate all the good info! It looks like the orig updraft manifold will fit on the 261-however research shows a Rochester updraft carb on the original. I can't even locate a picture of one let alone purchase one. Just use a Carter? I think if I go the downdraft way I will have to cut/modify the cab to make room. Any ideas welcome. Thanks, Chaz
