Replacement pad for gas pedal '03 PreRunner??

Anyone have any ideas on how to replace the rubber gas pedal pad without having to purchase the entire accelerator pedal assembly??
This is on a 2003, Tacoma PreRunner 3.4

 

I don't think there is a rubber pad that goes over the pedal.

 

I know there's a pad for the brake pad (mine's an auto) but haven't seen anything for the gas.

 

Way back in 2008 I went junkyard-dogging and got a floor-mount gas pedal and its floor pin bearings that attach the pedal to the floor out of a 69 Buick. I had to fab a mount through the floorpan to secure the bearings that snap into the base of the pedal. Almost 10 years old this little mod and works perfectly. I did it because I prefer more pedal under my foot than that tiny stick they call a pedal. Luckily my '16 RX350 has one like this factory-gee I wonder why??
