Looked, but did not find, so beeped it all out.

Delphi 85mm 5-pin MAF is used in trucks, Z06 and is the base for
SLP and the Granatelli "low cost" 85mm MAF

Delphi 76mm 3-pin MAF is used on '98-'02 F-Bodies and older
Corvettes.

This info may let you wire up your own harness or use these MAFs
in other applications (my purpose for doing this was to use the truck
MAF in a "ghetto flow bench" I'm building).
