So I passed on the 87 Starion limited slip but have an excellent opportunity to pick one up frm an 88. I know that they changed the diff mid way through the model year, but how can you know if the diff is the old version or the new version. I searched all the archives and the only thing I found was mention of a six bolt vs a four bolt pattern to the diff. They guy says it is a six bolt and gave me these numbers off the diff:

MB290946
á
8D06(DC1)4á

Any help would be greatly appreciated.
