I think you can blame Norm Grabowski's "Kookie's T"... which was on a leading TV series, 77 Sunset Strip.... and the resulting surge of 23-25 T-bucket kit builders.
The '26-'27 was just never a fad like the "fad Ts" of the time. Hey! I bet that is why they were named that. :-)~
There were a few well known drag cars, but the '26-'27 is an oddity today. ...a good looking oddity though!
