63 C10 gas pedal conversion questions

[Rusty one]

I'm starting to work on my 63 Fleetside project and I'd like to get rid of the mechanical stock linkage and get a drive by wire setup. I'll be running a 283 tripower with a 200r4 trans.
The location of the stock pedal assembly is in a weird place...it not flat on the floor but more on the side of the trans tunnel or should I say next to it.
Anyone using a drive by wire setup? If so for what model year vehicles did they get it from??.post some pics too. They really help!
Thanks in advance..
