8.5 mm wire retainer ?

[Aarons Air]

I'm installing a set of msd 8.5mm spark plug wires on my 383. I need a set of wire retainers for the corners of the valve covers. Will 8.5mm wires fit in the replacement factory style ? Or- what works well ?

Just if you enlarge them enough. I used stock brackets with 8 mm firecore wires and had to enlarge the plastic pieces. Metal brackets didn't need any job, but maybe 8.5 could need

I called a Mopar speed shop by me. They couldn't suggest anything. Surely i'm not the only one to encounter this? I haven't seen anything by Msd.
