Just bought a MAF on line that was supposed to be a 3.5" 93-97 F-body, but what showed up is a 3" & my book doesn't show the part number.

The number on the UPC sticker is:
83180008682
The number stamped into the plastic sensor near the connector is:
95046 8316 1

Can anyone tell me what this thing is supposed be for?
Thanx

 

Those don't appear to be part numbers. Are you sure it did not come of a B-body? I think they are smaller.

 

I'm thinking it either came off of a B-body or an LS-1 or something similar, because any mid-90's F-body LT1 MAF I've ever seen is 3.5".
That's what I get for buying off of eBay...
