When I was doing my research for this thread, I remember reading that the 80 Series LC wheels WOULD FIT over 231's with a 1/4" spacer, which is why I listed them as fitting with "at least a 1/4" wheel spacer".
Now, that being said, I cannot find a post/picture/forum member that can verify with photos and/or 100% certainty that his setup will work. Everyone running the 231's w/LC wheels that I can find is using 1.25" spacers.
This question seems to be coming up alot, so maybe I'll just test it out myself. I could pull an 80 series wheel off the '97 and try to install it on the '01 with 1/4" worth of washers on the wheel studs. Then we'll all know for sure.
