filler neck gasket...is this the right part?

if by chance, i put the grommet in and it turns out to be the filler neck that is leaking, will the filler neck from a 3.8 work? i have one ive been parting out and i could just use the one of that car if thats the case
 
I believe thats the correct gasket. I worked parts at a Ford dealership for a few years and sold more than a few of those. They are a common replacement SN95s. As far as the filler neck goes, I dont see any reason why it would be different. Probably will work.
