Well I got both done. I wasn't able to put the U-bolt on the outside on the driver-side spring because there was a small bracket to hold the brake line to the axel housing I didnt want to mess with for now. I am going to just order 2 more U-bolts and replace the T-bolts all together. It was a pain to replace these things because the rear shackles are so close to the gas tank I really had to play with the spring flex and position to line it up enough to ge the bolt through. Glad that's over! Thanks!
