Thanks to my buddy Martin, it seems I may have bought a "damaged in transit" new front bumper for the truck, to replace the one it wears now.
Martin bought a Tripple Chromed Premium bumper from the USA and on landing here in the UK it fell from the top of the container, resulting in the one tip being bent in about 35-40mm which means I now need to pay the price and then need to straighten it out as much as possible with a press or in a vice, appropriately protected.
My existing bumper is good, as can be seen on photos, but it is not great. So I will sell it on to cover some of the cost of the risky repair.
Little by little the bits are comming together.
