Evening All.

I have just bought myself a pair of 4 point harnesses, and im going to mount the rear strap eye bolts into the seatbelt mounting holes for the rear seats... as theyre spare now i have no interior at the back.

Anyone know what size the thread is? A quick google shows that the older fords used 7/16 unf but i dont know if that applies to newer ones.

Oh, its a mk4 fiesta, 1998.

Thanks,

Matt
