The small ring Mexican Mauser will fit into stocks inletted for the other small rings (93, 95, 96 Swede), but may require some minor inletting.
I've been looking at replacing the synthetic stock on my 1910. Boyd's and Richards Microfit both offer what they describe as fully inletted stocks for small ring Mausers, but they are inletted for the stepped military barrel. If you have a sporter barrel, you'll have to get a semi-inletted stock, or fill in the gaps of the stepped stock with bedding (I wouldn't go this route).
The scuttle butt I've been picking up off the net has me leaning towards Boyds. Lots of reports of Richards stocks taking a lot of extra work to make right.
