Fuel tanks?

Should be the same, I think the only difference with any of them, might be the fill tube, and the covers. But any tank from a 79-93 4cyl/v6/5.0 should work no problem.

IIRC the fuel tanks from 79-04 are the same with the above changes in filler tube and covers.

79 and 80 tanks are smaller 13 gal and have larger diameter filler pipes, than 82 and up tanks which are 15 gal. Not sure of 81. The fuel pickup and gage sender are in the same unit on 79-82 carbed, but different in later ones, where the fuel pump and gage unit have separate openings. The 79 pickup will not fit an 82 tank. Filler necks from 82 to 93 interchange. The early and later tanks will fit the same straps.

I would get as late a one as you can. A new 82 Spectre tank was $105 at the zone a couple weeks ago.
