Reversing sensors for my 61' Plymouth Valiant

Checkout proxel.com

Proxel advertise car parking sensors - see model EPS-DUAL 4.0 . I have been advised that the parking sensors can be used on steel bumper bars - but you need to completely insulate the metal bumper from the vehicle body by using a combination of "top hat" and/or plain PLASTIC OR RUBBER washers. See attached photo.

Has anyone used the product?

Thanks.
