So I'm going to replace the gas tank on my 71' as part of my on-going restoration.

I believe my the tank capacity for these years is 18 gallons, will a later model 78-82 24 gallon tank fit? Has anyone done this or even tried?

I already removed my spare tire and will be switching to ride tech in the near future so no concerns if it takes up a little more space underneath.

No I don't car about it not being the right tank for that year, but I do car about getting an extra 6 gallons if possible.

thanks for any feed back

In 78 they changed to the greenhouse rear window which allowed more space for a larger tank.

I don't see how you will have enough vertical room for the larger tank.

I would research what early c3 race cars have for fuel cells...you can probably find something bigger...unless they cut into the back to get more room....

No. Filler neck location on the tank changed beginning with 78.
