New/replacement parts for Hayman Reece towbars?

[Sick Puppy]

Hi everyone, I've been given a towbar for a 2004 corolla wagon (ZZE122R), and need the bolts & mounting plates etc.

I've tried to purchase these from one of their stockists, but was told that Hayman Reece will not sell replacement parts.

Does anyone have any ideas or advice please, e.g. alternative parts, contacts, or should i take the bar to an installer and see if they have parts to fit it?

Advice and suggestions are appreciated, thank you!

Surely bolts will be conventional grade 8.8 bolts, and any competent engineer should be able to knock up plates quickly.

Quite possibly lol Wanted to see if I could get the OEM parts first
