pretty sure i've seen it done...but i would have no idea where to find the pics
since the accord and the TL are the same car, it should be close to bolting up.
the biggest issues you'll have are that the bodylines are different and the TL is like 8" longer than the accord...though the length issue is mostly in the front end anyway. so in other words, you may have to move the crease on the fenders. that alone would be enough to turn me away, if not to try to find a way to use the accord fenders.
just go buy a TL. it'll end up like the civics with bmw fronts or ISs with a benz s-class rear...the car will be worth less
than stock, no matter how much you spend on it.
