Every dang issue i receive from both of them all they show is late 60's camaros, chevelles, novas...etc. has a TR ever been featured on the front page of either of these two magazines or ANY magazine for that matter besides GM high tech?
My guess would be because Jegs and Summit catalogs are printed to showcase the products they sell and they sell a ton of Ford/Chevy stuff. Unfortunately they do not sell too many TR parts so it wouldn't make sense to put a TR on the cover.
