They are simply '73-'87 Truck stands. They will bolt in place of your engine stands just like factory. The adapter plates are Trans-Dapt 4572.

Maybe more info than you're looking for, but someone else might be able to use it. This should be the same for nearly all LS variants '99-'02. From what I have seen, there are slight variances between where some of the grounds and 5V reference power is on the PCM, but the meat-and-potatoes are all the exact same.

These are the red and blue PCM connectors on a truck. Some of the extra unused pins will be diffrerent between F-cars and 'vettes.

The highlighted yellow portions are must haves for the engine to run:

- Idle Air Temperature Sensor (IAT)
- Crank Position Sensor (CKP)
- Fuel Injectors
- Throttle Position Sensor (TPS)
- Knock Sensors (May run without them, but why?)
- Cam Position Sensor (CMP)
- Ignition Coils
- Oxygen Sensors O2 (Front- rears are emissions only)
- Manifold Absolute Pressure sensor (MAP)
- Mass Airflow Sensor (MAF)
- Idle Air Control Motor (IAC)
- Engine Coolant Temperature Sensor (ECT)

The highlighted green are extras I will be using for convenience:

- ALDL Serial Data to hook up a scanner
- Fuel pump relay control
- Tach output
- Alternator turn on
- MIL/SES Lamp
- VSS Signal (helps with idle w/auto tranny and output for speedo)
