I see bro, but the problem is that the ones I have seen on ebay/amazon are not the same size (even the circumference which is the most important part, is not the same)
I did not mention ebay or amazon. I mentioned a speed shop; Andy's Autosport.
With the BRS Tuning fender Flairs, you would need to have them custom molded to your fenders, in addition to having them cut for your front and rear bumpers. You would also need to have additional bondo finishing work done to smooth out the fiberglass with your Celica's sheet metal and urethane front and rear bumpers. There was a reason why a 4-piece set of BRS fender flairs was sold for only $80 shipped -- they were mostly just a "template" piece for custom body kit fabricators.
They were never a simple "paint, then bolt-on and go" solution. You would have better luck with an entire wide-body conversion, such as APR's GT300 ( https://www.celicahobby.com/photos/celica/feature/apr-gt300/
) which was also created by Mike B. (BRS Tuning)
This is the Celica with just BRS Tuning's fender flairs, before it was transformed in to the widebody GT300. Yes, this is the exact same car. It was silver before having the work done, and then being painted red.
Notice how just painting and then installing with screws, leaves gaps and prevents the bumpers from being removed.
In addition, they also needed to be cut at a precise location for the fuel door.
Compare with its final transformation, in to the GT300-
HINT: You may have better luck finding Black Widow widebody fender flairs. They require less work for installation, than the BRS fender flairs.https://www.celicahobby.com/photos/search/BLACKWIDOW
