I just picked up a 1990 Celica GT convertible. Convertible was done by asc. I did a bit of research and I am not finding any info on conversations done on a 1990 but it has the correct documentation by asc. Any info would be helpful. Car has been sitting on non op for about 10 years so I have some work to do but it looks to be in good shape with 86,000 miles.
