Newt

Hi! I'm going to look at an 1980 Corolla KE70 this thursday, but i have heard that the suspension is different form the 1981 or is it the 1982 and 83 models? Does anyone know what was changed and which parts do I ned to convert the suspension on the 1980 to the 1981 (2?)? Sorry for my bad english, I'm from Norway... But this forum has more activity in one day, then the Norwegian forum has in one month, so i hope that someone can give me a good answer before thursday. :)
