‘E’ and ‘T’ Round Stickers on Drag Car Windshields?

[papajohn97]

In researching sixties super stock drag cars, I keep seeing these on the windshields on some reference photos:

Any ideas what they mean? ‘T’ for tech inspection? ‘E’ for eliminations? I have decals for these but would like to know what they mean before I put them on any builds. I welcome experts opinion on this and, lacking that, logical speculation. Much thanks!

T for trophy (class finalist).  E for Eliminator.  Couple of mine from the 70’s at Indy.

Cool! Thank you Ron! I knew there would likely be a subject matter expert with direct knowledge about these stickers on this board. I’m planning to model Shirley Shahan’s ‘65 Hemi Plymouth SS/A Drag-On-Lady and wanted to include these stickers on the windshield. 
So what were you driving and winning with in ‘78?

This is my less than average build of that car that started me on this model car journey about 4 years ago.

Awesome Ron! I was there and probably watched you run! I absolutely loved the S/S classes.

We also camped at the Clermont Lions Club park... We'll not talk about that... LOL!

Stayed there, also.  Atmosphere at night was a tad noisy and boisterous at times.  The food there was awesome and the people that worked there were wonderful.

You haven't lived, until you've spent a night in "The Zoo", in Brainerd!
