85 Diff..

The ratio in the 85 turbo cars is a 3.54 R200 unit.

The diff will fit...the rest of the suspension...extreme mods will be nessessary, and who knows how it will handle when done?

All turbo 300's had a 3.54 diff untill 1987..then they changed to a 3.7 lsd
Non turbos all had 3.7's tho not limited slip.
