LS series PCM mounting

[68 short step]

ive gotten a few questions on where/ how i mount my PCM for the LS (4.8 5.3 5.7 6.0) engines.... i use the factory truck PCM mount, cut off the backside (so im left with a box)....then i make some angles, one side 'rests' inside the factory notch on the firewall (the one im pointing to), this also locates it...then you can either weld the tabs on, or drill holes in them and bolt them to the firewall.....the PCM simply slides/snap in the holder, makeing for easy removal if neccessery...
