1970 D100 Radio

I have scoured the internet, EBay, this forum and all the other forums I can find, and I have yet to find the definitive answer. What is the correct radio for the 1970 D100 Sweptline? I know most came from the factory with AM only, but some dealer options were AM/FM units. I would prefer the AM/FM so I can use my Sirius XM radio. Does anybody have the number for the right radio for this truck? I have many conflicting results from the above sources. This is not a concours restoration I’m doing, I just want it to be the right one. Any help would be GREATLY appreciated!!

I think most had this one

In the '69 Catalog, I only see an AM radio listed. It's a model 707 with the part number 2906502

This link shows 61 to 68 I think I seen a 69 one time with one

What does the holes for the radio dash look like
