M1 Carbine slide lock lost (Plainfield), help plz

[Fallowt]

I was cleaning a Plainfield M1 Carbine I've had awhile and somehow the little slide lock pin went flying somewhere. They're not expensive but I was wondering if the Plainfield model has a different fit issue for that part than other manufacturers or can just use the generic. Also, I don't know if it's the Early type or Late type part which are different. The serial number is: 78478
The spring is still in the handle, didn't lose that.

I see this on ebay:

I'm open to suggestions for the part source, but please also advise on part type I probably need.

Thanks!

Contact the seller whom you listed and pose your question to that seller...I do know that seller deals in M1 Carbines. As for the new or late type, I think it doesn't matter, as field repair packs were issued to the G.I.'s .

Will do, thank you.
