Are spider gear sets available for 8.5" 10 bolt limited slip rear ends? I am finding lots of spider gear sets for an open diff but nothing for a limited slip rear.
Have a corporate 8.5 limited slip in my '81 Firebird and the spider gears are shot.

No, They have been discontinued for many years.
You will need to find a USED 2 series or 3 series unit to part out.
we have 2 series unit complete used for 250.00 each
