Interchangeable Marlin parts ?

[Die Judicii]

Who can tell me if the lever/loop is interchangeable between the different calibers that are available ? ie: the big loop off a Marlin Dark series 45/70 into a Marlin 336 30/30 ? Cheers,,,,,

Below is from a supplier of custom parts. Aftermarket lever page.

WHICH LOOP LEVER DO I NEED?
1. Marlin “Rifle Caliber” models *mostly* all use the same lever based on their trigger plate + butt stock
- Marlin Pistol Grip Butt Stock Lever, Black (1895 45-70, 336 30-30, 308/338, 410, 444, 450M)
- Marlin Straight Grip Butt Stock Lever, Black (336 30-30, 308/338, 410, 444, 1895 45-70, 450M)

2. Marlin 35 Rem rifles need a special lever with an additional cut in the control blade for smooth cycling

3. Marlin 1894 “Pistol Caliber” rifles all use the same lever based on their trigger plate + butt stock
- Marlin 1894 Straight Butt Stock Lever, Black Nitride (357 Mag, 44 Mag, 45 Colt, 218 Bee, 35-20, 25-20, etc.)
- Marlin 1894 Pistol Grip Butt Stock Lever, Black Nitride (357 Mag, 44 Mag, 45 Colt, 218 Bee, 35-20, 25-20, etc.)

So if your dark and your 336 both have pistol grip stocks or both have straight grip stocks, then it would seem likely based on this.

Does anyone know if the Pistol grip lever is available as a part in Australia?
As in do you have any leads on anyone stocking this?
It will be for a pistol calibre .357 magnum
