Just dug out my spares. There's a small difference in the shape of the cutout on the bottom, but I don't know if it will make any difference in function. Don't have my calipers handy to check diameters, but I would guess they're OK.
Back off topic, I also believe there's simply no good reason to take a Winchester apart for maintenence to keep it functioning. I have a 1927 carbine that was a ranch gun in Az. When I got it in the 80's, it looked like it had never ever been cleaned in any way. The action felt like it was full of muddy crud, but it still functioned fine. It had seen so much use, the magazine spring was worn through in two places, and had been spliced together with sewing thread. It still worked. I stripped it down and gave it a good cleaning when I got it, but havent taken it apart since, and it gets drug around in the hills and as a truck gun quite a lot. If one chooses to take care of their Winchester, all that's really needed is a careful bore cleaning, some solvent in the action with a rag and toothbrush to clean, and a little oil. No need to take them apart, and zero chance of losing small parts.
In a late 50's NRA reloading manual, in the 30-30 section, they commented on the Winchester 94 (no mention of Marlins), opining that they were " virtually indestructible in service". That's been about my experience over 30-some years of use, and one of the most mechanically reliable actions I've used, including Mausers and 1903 Springfields. Several of the half dozen Marlins I've used have had several different mechanical reliabilty issues. In the common threads of "If you could only have one,..." I first think of the 94, largely because of the reliabilty, and because of the compact, thin profile that makes it very easy to carry in hand, and always have if needed. YMMV
