My friend who has provided me with my last two Westfalia's  has picked up a mid's 80's 4x4 Toyota van.   
He is looking for a set of seat hinges to make a bed/rear seat with.  I'm thinking he should get a whole seat 

A) Does anyone have a set of seat hinges they are willing to part with? 

B) What would be involved with installing a complete Westy folding rear seat in the Yota.   

I figure it has to be a Westfalia seat because of the narrower width of the Toyota van.
