that looks like what ive done on the fatsun but mine is a 310 cable. i put a 310 pedal onto the 1200 arm that bolts to the firewall with a spacer cos the 310 pedal was smaller at the pivot point. then i removed the threaded bit the old cable screwed onto on the firewall,drilled 2 holes and was done,new style acc pedal! this saved me from cutting a hole for the std 1200 pedal when i fitted the new carpet from a vt commodore.(i didnt think it would fit as good as it does but cut the carpet in 1/4s and trim edges to fit and it pretty much drops straight in!) anyway now i'll probly have to change my pedal assy again when the L20s in.
