HDK or Junior636 have tubular LCAs for coil overs. I installed a HDK on my Demon and it is nice. I had him change it a bit for my application.
I can sell you two used stock non tab LCAs if you want to go that route. They do not have plates.
BTW, the reinforcement plate goes on the bottom of the LCA and is to keep the two sides from opening apart. On the second pic that arm doesn't look too spread apart.
