EGR & AIR Removal and TB Bypass 93 LT1

Could someone point me in the right direction for EGR and AIR removal and the TB bypass mod on a 93 LT1? I've found write ups for other year LT1's but not 93s. Thanks!

The TB bypass is the same on 93 and 94. Remove the hoses from the two connections on the base of the throttle body, and connect them together with a 3/8" hose barb.

EGR and AIR are very slightly different on the 93 than all other years, because on the 93 the AIR and EGR connect behind the intake manfold. All other years, they are totally different systems.
