Older Savage 12ga repairs

[Bigg_Chris76]

Thanks in advance for any advice given.
I picked up a Coast to Coast Model 267H from my grand-dads storage unit. It seems to be in good shape except for two things

-The slide release only works when the gun is upside down (weird)
-The bolt(screw) holding on the buttshock is stripped and not all the way in. So it's hanging the stock on halfway

I found that I can get parts marked for the Savage 77 on http://www.gunpartscorp.com/Manufac...guns-40503/77ShotgunSeries-41385/77-34256.htm

I was wondering if anyone knew about a manual for this gun, or perhaps just a diagram(video?) of the trigger assembly. My searches have yielded nothing so far.

Furthermore, would it make since to just buy a new stock and part#78? or to try and remove the stock with the stripped bolt?

Thanks again for your time.

Update-

I managed to get the stock off, so that is no longer an issue.

The only problem now is fixing the slide release. The fact that it works as long as it is upside down to me suggests that it's probably just a part incorrectly re-installed after cleaning however many years ago. Any help or layouts?
