Searich the following thread in this forum " TMI Interior". In that thread Rambo posts a couple pics of some 67 buckets he restored with the sport covers. I think Rambo has done a few sets of seats with the sport covers. I know he has commented on them in a few threads.
Of course there is always the pro car seats which are less expensive but you can't get those with covers to match a 67 interior. Maybe matching the interior is not important to you? Those that have them say they are quite comfortable and supportive.
Actually you can get the procars with matching Chevelle covers now... OPG sells them...
TMI also sells an aftermarket reclining "modern" seat that has factory-ish covers on them- I have not seen these in person, bu they are tempting. I am inclined to like them more than the procar style which are a lot smaller than the factory seats were.. They look ok in camaros and mustangs, but seem really small in a Chevelle.
These are the TMI "pro-Series" 1967 chevelle complete seats:

They wind up being about the same price as restoring original seats...
But There is something to be said for having original seats in these cars... But as the number of available of seat cores dries up and their cost continues to goes up, I imagine those aftermarket seats w/ stock style covers will begin appearing more and more.
Personally I am not a big fan of the big side bolster option seat cover/bun sets on the original seats... Legendary and TMI both make them, and I've installed both.
I still prefer the stock seats when done right with the good, soft ACI Buns- and that is what is going on the bucket seats in my own car in a few weeks- Legendary Covers & ACI buns.
I will say that when deciding what to do in my car, I really REALLY looked hard at those TMI Pro-Series buckets. In the end i went with what I know will look and feel right in the car.
Anyway- sorry for the long winded reply...
