Ding-ding-ding! You are correct again sir! I got carried away by the nice packaging, but you raise one key point. It is not the original GM box, therefore whatever is shown cannot be verified as such... My first instinct was the same as yours, but got excited seing the NOS parts!..:)
Your thoughts regarding the original rear mount GM 60869 also make sense to me... I did find a casting and part number cross section in my book along with some deleted numbers but I did not find this one... I t has to be on a 39-40 book for sure... I just like to see the part number references and changes over the years...
Even though Steele rubber is pricey, I will check their listings for mounts. I know that their rubber is top notch and if not mistaken US made...
