Well, I did a vaguely similar thing on my Mark II.
I borrowed some calipers off a mate, and bolted them on. I then did some measuring and worked out that the DBA Pug rotors would actually fit without machining. I then got a set of the rotors and bolted them up to my factory Mark II hubs (note that the holes need to be ground out a little).
Bolted it all together, and found there was an ever-so-slight clearance problem with the calipers that was fixed with some high quality machined washers and an equivalen adjustment from the tie rod ends to fix the alignment. After that it went together fine, including the stock brake hoses - which I replaced with new items. With the age of your car, I'd say yours will be just as deteriorated as mine.
I was lucky to have a mate with the calipers I wanted, but in your case head to a self-serve wrecker with a bunch of spanners, some WD40 and a morning to spare.
Go find yourself a Hilux and pull a caliper off it. Go find an RT104, and see if it bolts on. It's all good and well if the bolt spacing lines up, but a test fit is the best way. As I said, my conversion had a clearance problem (luckily an easy fix) but I'd have been rather annoyed if I measured the bolt holes, bought a pair of calipers on that basis, and was then unable to use them!
Out of interest I am running the stock 7/8 master cylinder which bled out the system with no problems and came out to a good pedal pressure. Unfortunately the car is a long way from being on the road so only time will tell. I have a 1" master cylinder that I can use in it's place anyway, just trying to avoid paying for a reco and making up new steel lines if not required.
FWIW I paid $70 for a pair of 80-Series Landcruiser calipers. They are much the same as the Hilux ones, but with slightly different piston sizes. Make sure you jot down the model number for the car you got them off, otherwise parts may be a headache in future (unlikely but best to be safe!).
Don't forget to budget for a reco on the calipers & master cyl, fresh wheel bearings & grease (stupid not to replace while it's all apart), new brake pads, brake fluid, and as I mentioned new rubber hoses too.
All up my 'cheap' conversion was about $800 but everything is either brand new or reconditioned.
