Rebel,
For ease of fitting, the pump from a BA falcon would be better pump to use than the one from a late model commodore. The falcon pump uses 5 or 6 bolts to hold it position where the commodore uses a circlip. The fuel tank from the harrison now uses a falcon pump. The first few tanks that had the late model pumps that were made used a late model fuel pump from commodores(which I have) and then they were changed to the ford pumps.
The commodore sedan pump that I fitted I had to shorten the locating tubes by about 50mm to fit it into the tank. If you are going to fit a holden pump the VY ute pumps have shorter locating tubes than the sedans.
