I have a i400 that I just pulled the engine to replace the clutch. I’m having an issue finding the right clutch . All the ones that keep coming up are 10 spline. The one I have is 24 spline. Does anyone know of where to find the correct clutch?

Try looking for D12 series 3, s/n: 3000-up clutch and see if it looks like yours.
Here’s a link to one i found :

Your I-400 is essentially an industrial version of the D12, I believe.
I have no experience with the vendor in the link, so not sure of the quality of parts
