So I then realized I had a linkage throttle and I REALLY want to keep a somewhat stock look to my truck (no Lokar pedals or pedals that look like an aluminum footprint, thanks!) and the new motor requires a cable setup. Lucky for me, in '71 Chevy converted to a cable throttle and one can do a very easy and nice job if you've got a drill press and some files.
$24 scored me the accelerator assembly out of a 71 or 72 pickup and I was even able to use some of the bracketry to make my new retainer plate.

the above forum also has sections for other chevy pickups from '47 to present so if you have some questions about your other chevy truck (that classic hot rod pickup that wins awards, doesn't everyone have one? I sure wish I did! ) they are a great resource!
