ill be running 38.5" tires/4.10 gears w/ d60s
360 v8 welded diffs. will these joints be enough or do i need 1350s? thanx in advance

In a sammy, K20????? What does it weigh??????????

sorry
j-10 with bobbed frame/bed gone.
not sure of the weight but its not super light
guessing 4500-5000 pounds?

1330 might get it for a little while but the angle on that c/v is only 25 max- the one ton set up 32 degree's and its pleanty strong no worries- Jess
