Short answer = no.
Is your truck bagged? Then you need to weld on new tabs. Is it sprung? If so, the leaf spring mounts are close to the same width, and if you're ghetto you can oval some holes and bolt it on. But personally I would remove the leaf spring perches and put new ones on, sine they are only $20, or can be made for maybe $5.
Then you have to deal with the drive shaft. You need the Toyota drive shaft adapted to the end of the Mazda drive shaft. This will cost between $100 and $200 depending on it it needs to be re-tubed.
AutoZone carries some "Adapter U-joints" to adapt a drive shaft from one vehicle, to the yoke of another. Personally, I wouldn't to this, for a few reasons. I don't like ghetto stuff, and if it fails on a road trip or at a show, most places will not stock it, and you won't be able to get it changed. Auto Zone themselves has to order them.
As far as the front, swapping to a Toyota spindle is the ghetto way. You will create more bump steer than the Mazda has from the factory. They already have enough as it is, creating more will make it a nuisance to drive. What you need to do, is buy the machined hubs that TOYBOY89 on SSM makes. They bolt on, and come with a Toyota or S10 bolt pattern, and they come with a rotor you can get at any parts store, and the hub itself is machined to put the rotor in the correct spot.
That, or you need to contact Jon, laynrockers on SSM, and send him your spindles, and have them machined to accept a Toyota hub and rotor, and then space out your caliper.
