'87 SR5 Turbo - Which Ring Gear for Rear Diff Gasket

Hey, my rear diff on my '87 Turbo is leaking slightly. I called Fel-Pro (www.felpro.com), but they didn't know if I needed:

RDS 55431: 10-bolt holes; Toyota; 7.8" R.G.

OR

RDS 55430: 10-bolt holes; Toyota; 8.9375" I.D.

Which one of these do I need for the turbo rear axle? Thanks!

Gaskets for service as this are obsolete.

Cleaned and degreased surfaces with Permatex Ultra-grey. Never leak again.

I’m up for that. I was just following this thread:

I can do Ultra-Gray if it’s strong enough. I assume you do circles all around the bolts and single lines everywhere else?

^^this^^ I have pulled and reinstalled several 3rd members. Always used some form of permatex. Never had one leak. Pull the 3rd, clean both surfaces , apply sealant, reinstall and torque to spec

The rest of the steps in the thread above still apply I assume? Pull shafts, pull 3rd, etc.
