Securing a Sink in a 1971 Westy

[RayHutch]

Hi, how is the ply sink unit secured in a 1971 Westy ? I notice that there are no bolt holes in the floor of my van. Does it secure through the metal behind the seat?

I have a later sink that I am adapting.
Thanks

Yes, it is held in place essentially by two bolts through the bulkhead. Some units have an L-bracket onto the floor as well, in the walkthrough.
