Double front seat in 806/807

Don't think the 807 had an E7 equivalent taxi version as it was a larger body based on the Expert. A double seat from an E7 would probably fit but I guess it would not be straightforward needing careful cutting etc.
Reliable 406 would know better than me.

806 is easy you just get a double expert seat my friend had that in front and a rear bench making it a 9 seater !!but the E7 taxi has either no passenger seat a drop down single or a normal single depending on where it is as different councils have different rules on front passengers.

Not sure later expert or dispatches came with double seats but if they did it probably would fit
