Aluminum Shafts

Ok. Thanks for the input - umm I mean info. I have 3 trucks under construction. One is a Lightning/GA with tall titanium towers, 6 spider diffs, Ultrmaxxed transmision and 8 Kyosho 8th scale shocks. I want to use it to pull the others on a trailer.
The second is a cf Gorrila chassis with FLM hybrids, 8 spider diffs and low ti towers. I'm trying to find 4 UE shocks for that one. It will be a single-speed racer.
The third will be a stock chassis basher with RPM arms, FLM Combo bulks. Nova/Robinson diffs, and a ti rollcage.
I guess I need to dump all the aluminum shafts I've been collecting.
