70's tank in a 68?

Tank Height

Does anyone have dimensions of the 20 gal and 22 gal tank? I'm looking for how high they stand above the flange. The top of the '68 tank is basically flush with the flange, and is the lowest point of the trunk floor. I'm guessing the 20 gal tank is a couple of inches taller, and might be a good fit for the '68 floor, maybe making everything closer to level.

Thanks,

Andrew

Easy to guesstimate. The 70 tank top was level with the trunk floors. The 69 was about halfway between the 68 and 70. The bottom, of course, was the same 64-70.
 
Nothing wrong with a bigger tank - helps launch, weight distribution

the bigger tank should help weight distribution, too . . . nothing wrong with adding a little useful sprung weight to the back there. It should balance the car better and give you more cruising range and less time at the pump . . .
