LS3 Accelerator pedal sensor options, installation

[Mastertech5]

Anyone that installed a crate LS3 with ECU or bought a stand alone GM ECU that came with the gas pedal, how did you mount it (too big) or what pedal/sensor did you use that fit? I remember Street Rod Jim mentioned having to get one for a corvette. Do you think any GM pedal that fits will work with the electronics? I tried to fit it today and there is no way it will work unless I made a different metal bracket and cut about 2" off the bottom of the pedal.IMG_20221206_135214_hdr.jpg IMG_20221206_135229_hdr.jpg IMG_20221206_135254_hdr.jpg
