early A v-8 throttle setup - need pics please!!!

i just bought a early A body cable throttle pedal setup. i see how it attaches to the firewall but the problem i'm having is with the pedal. i have a pedal with a tab with a bushed hole in it but the swing-arm looks like it has a roller assembly on it. do i not have the right pedal??? it doesn't seem to work right if i use it without the roller (i.e. with the swing-arm through the hole in the tab) and the tab/bushing piece interferes if the roller is used. so i'm hoping some of you guys with stock v-8 cars can post some pics so i can see what it looks like from the factory and go from there. i think maybe i have a 6-cyl pedal with a v-8 cable/firewall bracket???
thanks!!!!!
