Welcome here. I would try our sponsor at the top of the page, NOS Reproductions. I am pretty sure they can help and you will find the service there second to none.
By the way, are you aware that when you order any chassis stuff from any suppliers you specify for an 69 full size Chevy, not a full size Pontiac? You may well be familiar with the fact that your car rides on an Impala chassis but if not, it does, and many suppliers, especially in the US will not know this and try to sell you US Pontiac chassis parts which are not the same at all.
