I had found this site about a year ago and had been wanting to do a lot of what it teaches you. I have an '82 Celica GT and considering that the Supras and regular Celicas were nearly the same, these instructions work great with the first project I've done thus far in completion, which is the change in display lights. I used to have the stock greens, but now I have blue in them and will be checking them out tonight.
Anyway, thought I'd share this site to anyone else that has an early 80's Celica or Supra, or any other year and model that you guys think this stuff will work on. Hope it helps!
I'll also see about doing up my wheels as the guide shows. He has two pictures to compare his old wheels with the new ones. I plan on doing the same thing with mine at some point. I did try to half ass sand them down, which helped a lot in cleaning, but there's a lot more room for improvement. Any other sites like this for an 82 Celica would be great too and any ideas anyone could throw in. Thanks.
