Well I will be the 6th to chime in

No one yet has out right praised the Trail
3/4 link kit. If you want links done right get the 4WU kit's. Or if you can do the math yourself get a Ruffstuff (or other vendor) generic bracket kit and set it up yourself.
If the $ or time/ skill of a proper link kit scares you, then get leafs. You can save $ and run RuffStuff (or other vendor) brackets and used leafs, or Allpro leafs. Either way I would suggest against getting their (Allpro's) complete kit as it is over priced and you can get many of the components (ie brackets) from other sources for cheaper.
