BudsGunShop.com - Marlin 30-30

On limbsavers website it has downloadable template that shows the shape and size of all their pads it also gives exact dimensions that you can then measure your stock.

I would check that out to be sure it's hard to say without know the exact measurements or model of your marlin.
I did find on another site that the limb saver model "Limbsaver 10102"
Will fit Marlin 444, 450, 336 and 512 with wood stocks (most models)
The one your looking at model 10801 measures 5.095"× 1.775"
The model 10102 measures 4.70×1.6"
So if you print the template for those 2 you can compare it to the size and shape of your stock.
Sorry I couldn't give you a definitive answer but hopefully that helps have a good day and good luck.

Tony, this model does fit the lever 30-30. It fits snug which I liked very well. Cheers and stay safe!
