CT1 and DT1 same gas tank? was created by eddy20

Are the CT1 and DT1 tanks the same for model years 1969-1971 Badge bikes?

DT1 is 2.4 gallons, CT1 is 1.9. It seems to me from reading posts in the past that they are not interchangeable.

Smaller & probably shorter by a bit but fits on ok, well does on my RT2 frame--as seen. Yes it is an RT2 frame even if it hat a Triumph 3TA motor in once lol. I shortened the subframe about 35 years ago.
