Borrow 2 4x100 15 inch wheels near Ballybofey, Donegal

[Davemx-5]

Folks,

Have the nct on my car tomorrow at 2....bought two pairs 15 inch wheels.

Checked one wheel in each pair and they fitted the 4x100 test hub.

One of the wheels in a pair turned out to be 4x108.

I'm now badly stuck as the garage is closed.

Anyone able to help me out?

Cheers!
