Im planning to build a set of long arms for my xj similar to the rcx, and tnt long arms. Im building the lowers out of 2" DOM with 2.5" JJ on the frame side and rubber bushings on the axle side. I noticed that t&t, RCX, and rustys use smaller 2" wide joints on there upper arms where it attached to the lower arm. Can I use 2.5" johnny joints on the upper arm or will I run into any issues doing this? Also any pics of your homemade longarms would be great. Thanks
