or do what I do.
do it in stages, remove all parts and categorize them - like all removed screws and panels should be taped to large paper with descriptions.
Remove wiring assemblies intact
remove powertrain unit and cooling system
keep all at home and work them on your own in your own comfortable time.
let the guy redo the body shell - if you have a separate paint person, make sure he talks to the guy redoing the body shell.
This nissan rusts from the roof pillar joints due to the rear glass rubbers shrinking and leaking - the factory used butylmastic compound beneath the rear glass to prevent this leak - same compound they used to seal the mudguards to the body. They also rust at lower seam panel of floor and rear face panel at the joints due to shrunken body sealer (age) and mostly diesel and oil paalish wali tasali baksh service. (but never greasing the ball joints and tie rods LOL)
The wiring is very very simple it comes out in 5 pieces total, - place it on a table (shaamyana wala rents them) - and rebuild it (youtube how to splice wires and how to wrap) new connectors and pins are sold in Plaza market and co-operative market.
the A12 engine is very simple to rebuild - and lots of spares sold - infact some shops near lasbela also deal in exchange A12 engines - they are fully rebuilt for taxi purpose. I still like to redo the original one (better outcome)
once painting is complete - redo the finish parts yourself which is a long process itself if you are careful with noise dampening etc - e.g. using the original white push clips for door cards etc.
.Call Afzal at AH sons and ask to redo the front struts to "factory wali setting" - you will need to buy new springs though - rear shocks are simple, Afzal can "make" you a set of new rear shocks but would be more expensive than new ones in plaza, but worth it - he wont make them for everyone though due to price.
All lower bushings are available for this model, make sure to replace all and tighten them properly with loaded suspension, not hanging suspension.
