hey all, i recently thought it would be a "great" idea to upgrade/replace my stock intake manifold on my 235 w/ a offy 3x1 w/ 3 matched 1bbl rochester carbs. i got a great deal on the intake w/ carbs (120 bucks), so i felt i couldn't pass it up. the only thing missing was the linkage which i am finding now to be nightmare to find. i would like a progressive set-up, but if not straight linkage will do. does any one have any info on this? trying to find this stuff online or on the phone is a full time job in it self. any info is greatly appreciated. thank you -DVZ
