d16z6 to d15b swap questions

is it a direct swap?, I found a d15b at the scap yard for $100 and scooped it up as a replacement motor while I build my z6 or b16
last question: what is the proper way of removing an axle out of the tranny?, just pull it out or is there a special way?, also how do I reinstall?, just push back in bolt the boot down and pump full of grease?
any helps great
