What do you mean by dismantle? Remove the airbag module?
Most of the 91 volvo's airbags were not standard. However you can take it to any volvo dealership and have them add if you do not already have them.
There are four and disarm with screwdrive for the seats and remove fuse and disconnect batt.
depends on the year. my 740(1990) has none!
2003
They have driver, passenger, and front side airbags (located in the seats)
Airbags are not in the door, but rather in the seat. Should be no additional issue at all.
you have to take the starter out of the car and dismantle it.....it's an integral unit
