I bought a brand new 28 spline trac lok from Latemodel Restoration Supply, 10 years ago :S for $190 shipped to my house. Scott (Lincolnmania) installed it.
Never rebuilt one, and if I could find one cheap I'd rather replace than rebuild.
The lunch box lockers (fit in an open carrier) have mixed reviews. I haven't read much about them being used for cars and racing, primarily off road stuff. Seeing as you have a 5 spd, a locker might be okay. Depressing the clutch will unload the driveline and unlock the diff. Lockers can be a little lame in automatic cars, as its hard to fully unload the driveline (short of shifting to neutral). Parking lots and tight spaces are usually accompanied by tire hop and scuff.
A spool has no place on the street. None. If you put one in, budget for axles, a limited slip/ locking diff, carrier bearings, and additional gear oil and additive. If it doesn't break the axles, you'll hate it to the point where you'll end up going with a street drivable diff.
With a spool, the axles go through torsional wind up cycling all the time. If you don't know anything about machine parts design, EVERYTHING is life cycle limited. And if you're starting with 30 year old axles... good luck!
