Welcome to the site..... Good luck finding that gas tank, it's probably not going to be an easy find.....
Welcome to the center of the Maverick/Comet universe!!! Try posting an ad in the "Parts wanted section" you might get a hit or two.Good luck!!!
I am not sure but somebody here might know. If a fuel tank from a 69-70 Mustang will fit you can buy a new 22 gal tank at Parts Train for $140 plus the sender and staps. Just a guess but if it works it will get you on the road and for longer periods of time
The 1970 takes the drop through the floor type tank not the strapped under the floor type. It was the only year Maverick that had that tank.
Welcome! Here's an ad for a complete 1970 Maverick in Maryland, which is far away, but you never know, it's only $750, and you might use some of the other parts too: http://buycarandsellcar.com/listingdetails.aspx?id=782293 Looks like a recent listing, but if you're interested, you'll have to call to see if it is still available. Good luck!
Here's 2 more full 70 Mavs listed on craigslist: http://denver.craigslist.org/cto/1816357269.html http://minneapolis.craigslist.org/dak/cto/1824801654.html I saw many more, but they are alot more expensive, and far away from you.
If it is a drop through then that probably widens the list of cars that might fit. 60's Mustangs, Comets and Falcon had drop throughs. I know they repop a lot of Falcon and Mustang stuff and tanks are one of them.
It's been talked about before. It can be done but, to use an early drop in Stang tank, you would have to change the configuation of the square well that the Maverick tank fits into. Since they don't re-pop the Maverick tank, you're stuck with finding a good donor or having your own renewed.
