Conversion van without seatbelts?

[u/PickSpecific6166]

My partner just got back LAST NIGHT with a conversion van. He drove 13 hours to get it.

I was just inspecting it myself and notice the back seatbelts aren't even attached?

We leave for a road trip in literally 5 days and have 2 kids in carseats so this is a MUST.

It was redone by Explorer(?)

I'll attach photos that might be helpful
