So it looks like there is minimal wear to the ring gear and pinion
gears. Just a few minor nicks but not on the gears themselves, more
on the body of the gear where it would not come in contact with
another gear. Is it possible to just pull the ring gear and easy out
the studs and install new bolts and be good as new? Or is this
something I should leave this to the pros?

I wouldn't guarantee the job. You can't tell about wear to the ring and
pinion unless you have looked at a lot of them, or when you hear the howls
of protest at road speed. The bolts are hardened and many are left hand
thread. Pay particular attention to the number and position of carrier
bearing shims, and use high strength thread locker on the new bolts. What
you are proposing is "possible" but a replacement open differential carrier
probably wouldn't be expensive enough to justify the effort to drill out the
old bolts.
I don't have much problem swapping in a new carrier, for example to get a
locker or limited slip, but there is some expertise involved and I wouldn't
recommend that an amateur attempt it if there is the possibility of existing
damage.
The major part of the cost to get this done right is in the ring and pinion
set up cost, which is best left to professionals or at least those with the
proper special tools. 4x4 specialty shops? Heh, better go for a ring and
pinion specialist.

I wouldn't guarantee the job. You can't tell about wear to the ring and
pinion unless you have looked at a lot of them, or when you hear the howls
of protest at road speed. The bolts are hardened and many are left hand
thread. Pay particular attention to the number and position of carrier
bearing shims, and use high strength thread locker on the new bolts. What
you are proposing is "possible" but a replacement open differential carrier
probably wouldn't be expensive enough to justify the effort to drill out the
old bolts.
I don't have much problem swapping in a new carrier, for example to get a
locker or limited slip, but there is some expertise involved and I wouldn't
recommend that an amateur attempt it if there is the possibility of existing
damage.
The major part of the cost to get this done right is in the ring and pinion
set up cost, which is best left to professionals or at least those with the
proper special tools. 4x4 specialty shops? Heh, better go for a ring and
pinion specialist.

Just an update....
I did the repair myself and all went well. Unbelievable that no gears
were broken or chipped with the bolts laying in the diff case.
All is well and I am back on the road again.
I appreciate all the advice.
