I think I got lucky with that stock van part curing my problem. You may need to weld an extension on to yours and experiment a bit to make it work.
I built 5 or 6 brackets for the manifold before I finally got one that put the kickdown and the throttle cables in the right place, and I built 3 different brackets for the throttle linkage on the carb itself.
I was really happy I didn't have to do that on the Trans side, that would have been no fun in the confines of my Trans tunnel.
