i have an 89 toyota 4runner and am planning a solid axle swap with a toyota front axle.  i plan on running either a mild (mud terrian style) 38 inch tire or a 35 bogger.  i am wondering which route for axle shafts i should take in terms of strength and reliability.  should i go with the longfield 4340 30 spline shatfs with birfields or go to yukon gear & axle eliminator kit which is also 4340 but removes the birfields for rebuildable U-joints built by CTM Racing Products. any help would be greatly appreciatied thanks alot
