Van,
I had to disassemble the spring packs to add the inserts. I cut them to the length of of the spring below it, once cut I reassembled the springs and banded the ends. I borrowed a banding machine from work, made the a lot easier. I had to find a grade 8 bolt the correct length as I removed 3 leafs per side.... Around here we have Tractor Supply stores, you can buy 90w in quarts there.
