14x8 on Stock?

This is probably in another thread, but I have to make a call pretty quick.

I have a 69 Dart four door with an 8 3/4 rear end. There are currently 14x6 Cragars on it. I have an opportunity at two 14x8 Cragars for the rear.

Does anyone know if these will fit without modifications, or is the question a bit too vague?

Thanks in advance.
I will say no. Not without trimming.
