i know here in the states the mkii's, cressidas, and front 4x4 diffs are all 7.5in. what other toyota modles have 7.fin r&p's. there was a site posted in the suspension section for cusco bars. the site also sells trd lsd's. if there is a japanese modle that has a 7.5in lsd it may swap in(soarer, etc...). the prices arent bad. most lsd's are ~$766 usd.
