just dont.
ive been working on mine for a month and its still not completed but heres a quick run down.
what you need:
2 doors and two spare
some 5mm angle bar (prob over kill but my local only had 3mm or 5mm)
5mm flat bar, or flat stock as it may be called.
4 driver hinges
4 passenger hinges.
what to do:
set the door up on its factory location, gap it up and make sure it sits right.
swing the door open and cut out the back of the door jam on the cab and cut round inside till prretty much the back. please remove all interior and seat belts while doing this.
take the doors off
cut the spare passenger doors hinge side off and set it on the back on the driver door. you will need a picking hammer to get the lines to match probably.
keep the standard hinges on and remount the door
get inside (i did mine with no rear wall so acess was easier) and mount he flat bar inside the pillar horizontally, i mounted mine on to of the seat belt mount becuase i didnt want to move it.
get the angle out and place it where it needs to go and mark on the angle where the bolts need to go
go over to the drill press and drill out the holes. think its a 8-9mm bit for toyotas.
come back and weld the angle in, bolt the door on, unbolt the factory side and swing it, please hold it while you do this as it may move. check how it swings, at this point u will probably have to increase your back door gap by 5mm, so do that and see how it swings.
ok thats all good weld it in and grab some 3mm flat stock and tie the angle back in to the factory pillar.
then gran your spare doors again and cut the striker plates out, weld the passenger one on to the driver door on the previous factory hinge spot, again you will need a picking hammer and small filler plates.
cut the striker latch hook things (cant remember thier name) off the old pillar section and now weld them in to the A pillar, you will have to mount the door again to see where it all goes.
do the same on both doors, weld up the original bolt holes on the a pillar and then resheet the b pillar and make a new jam, im up to that stage.
here are all the pics i have, im keeping it to a minimul because here in australia people always talk of it but dont do it, i think im one of a handful of people thats done it locally and i dont want to post 1million pics and have everyone ripping the way i did it off and making out as if thier some genius
oh and severed 701 also did this, u can maybe contact him on street source.
new A pilar
striker plate on new side of the door
hinges taked in thier new position
://i160.photobucket.com/albums/t200/Th0m_/Image092. see how it swings differently
as for that shaving i know it was hack so i redid it
hope that helped some, i dont mind these photos been passed on as i dont post on SSM anymore, only here and downundertruckin.
cheers
