The Maf unit is all standard I would rather sell it complete look make me an offer and if its reasonable you can take the intire thing, you probably better taken the whole unit for spares. The injection system also comes with the electronic distrubtor which is worth a few hundred second hand if you can find and v8 one.
Rollin: Ill have a Maf sensor avalible in a few weeks time. It'll be the stock V8 one. I dunno if you'd want to use it on a 6 as I think theyre a fair bit smaller than the throttle so would be a bit of a restriction.
