I'm running Moser 35 spline axles on my 95 with c-clip elims. You can get them from moser with the elims already pressed on and ready to go. If you use elims though there are a few things you will need to do. You will need to cut the seal flange off the axle, this can be done with a sawzall, hacksaw ect ect.... Cut it off flush with the brake mounting flange on the end of the axle and smooth out with a grinder. You also need to have the brake mounting bracket machined to accept the elims. Finally when you re install the calipers you may need to grind the mounting pads a little so everything will line up nice. Don't forget to use plenty of sealer between the axle houseing flange and the caliper mounting bracket and between the caliper mounting bracket and the elim. The axle seal is built into the elim. It's really easy to do, sounds harder than it is.
I'd suggest getting the axles/elims/and spool as a package deal from them. IMO I wouldnt use a mini spool. I'd also get a moser support cover too. I'd go ahead and get the 31 splines too. It's a pretty big investment, but it will be dependable and will take alot of abuse.
I got all my stuff from
http://www.holcombmotorsports.com/ They are local here in NC. Give them a call and tell them what ya need or look it up in their online catalog.
If your intrested, I'll see if I can dig up some pics of my install and post them. Good luck.
