Clutch help!!

I have a 1986 f150 4x4 5.0 with a 4sp np435. It’s time to rebuild the trans so I figured now was a good time to do the other stuff. I know they use either a 10” or 11” clutch so I removed the trans today and then the clutch so I could measure what I had. It measures 10 3/8 inches. So almost 10.5”. Does that mean I have a 10” or an 11”? Just want to make sure I get the right replacement when I order. Thanks in advance.

You are measuring the friction disc or the pressure plate?

Don't know what to tell you. They say in the descriptions when I look them up they measure 10 inches or 11 inches.

P.S. Does your flywheel have two sets of bolt holes for the pressure plate? Some do. The outer set is for the 11 inch clutch, the inner set for the 10 inch clutch.

Yeah I looked them up and that’s all I could see too. I believe if does have both sets but I need to look. Didn’t really pay attention when I removed it. I will head back out to look.
