If I bought a panel van (more than likely be a L2) and wanted to fit extra seats in the rear (like a kombi/crew cab) are there captive nuts in the floor already for these to be screwed into?. Also would it be straightforward to have a removable row of seats that could clip in and out of the rear of the van?.
Some vans do and some don't, you won't know until you look at the van you are converting. but if you assume No, then if you find any, then that's a bonus...!!
If you know where to look you may see if it has any or not, however," IF" it has any, some would be hidden by the fuel tank, and a some of them would be inside box sections. as I have said, assume NO,
