Which clutch fork do I need?

'78 F-250 4x4 SC with 351M NP 435 4 speed.. Actual build date of September '77. I'm replacing the clutch and related hardware, as my current setup is a mashup of 73-79 parts mixed together. My clutch fork I think is incorrect. JBG lists two different clutch forks for trucks with 351M/400. .......which one is correct for this application?

Thank you!

I don't see the 7515 listed in the chart Rich. Is the actual part number going to be the same as the diagram number, meaning the same for all engines?
Or is there an extension to that chart that shows the part numbers for the release lever?

Maybe the two different ones hail destroyer saw on the other site are for six vs eight cylinder engines?

Paul, JBG has a listing for "ball type" and non ball type both for 351m, based off the trucks serial number. I don't have the truck where I'm at to check it, and I think the PO had cobbled it together with junkyard parts, so I'm not sure which pieces are OE and which are aftermarket or junkyard pieces under there.
