those are from GT factory...they are nice but its a universal kit so I'm sure it takes some work to make it fit a celi, I havent seen any pics of that kit yet.
i posted the link up earlier in the thread
it IS a universal kit and you're probably better off welding it. they recently cut the price to $999, but it will take about $500-$700 to install it--so it comes out the same as the decah or verticaldoors.com kit.
if you pick up the latest "modified" magazine (SEMA on the cover) it'll have an add for the "GT Factory Diablo" doors. in the add they show a celica..and give about 10 or so pics of it. it looks very good in my opinion.
the people that have the kit love it for the most part. the shocks are stronger and the doors don't wobble as much as the decah, verticaldoors.com, or c2 kit.
but like i said..it IS universal and therefore you most likely will have to pay a bit for the install.
