Accelerator pedal question

[atm70chevy]

I have a 1970 C10 and am having a heck of a time finding the correct replacement accelerator. I ordered a 1970 pedal without doing any research and it is a floor mount pedal. My pedal does not mount to the floor so I thought someone must have changed it over to a 71/72 style pedal so I ordered one of those. It's not right cause the hole in the back of the pedal is much to small to fit on the rod. I was looking in the LMC catalog and saw they have two different style pedals available for a 70, one floor mount and one is not. Does anyone know if there were two different pedal available then???

Here is the link for the pedals from LMC. #12 is the pedal I think could be the one I need. http://www.lmctruck.com/icatalog/cb/full.aspx?Page=51

Thanks for everyone's help.....
