5 or 6 bolts flywheel to crank?

Did it line up before? The only time I ran into this is when trying to swap /6 and small block parts.

I'd try to find out which part is wrong first and I wouldn't attach a flywheel with 5 bolts, see if you can scratch up a v8 flexplate and compare it to the crank and flywheel to see whats going on.
