Need help

ok so I'm replacing my plugs on my 88 5.0 and I cant find two places that say the same thing for the gap? Anyone know it would be great.

Probably the best place would be on the under hood emissions sticker if its still in place.

Check the tag under the hood. It should say something like .045 - .055. Just gap them somewhere between there.

I just checked my Haynes manual and it just says to look at the sticker too, sorry.

I just checked mine it said .048 - .052. I'd gap them about .048. Once you put some miles on them they'll open up a little.
