Limbsaver pad for 30-30

[opie011]

Sorry if this isn't the right place for this, so please move this if need be.

I'm looking to buy a Limbsaver pad for my dads Marlin 336 and am not sure what size to get. I want to get him the slip-over one. Thanks for the help.

Compare the dimension and purchase the closest one if walmart, basspro etc don't carry the exact part #.
