Convince me to put a TKX in my Dart

Yup, I remember that brace, thanks for bringing it up. The top connection is really the only option I'm exploring, the BHS588 does nothing in my opinion. Nothing that the beefy lower section isn't already doing, that is.

I have to add though, THANK YOU for finding that unit I actually purchased. If that fits, I'm inclined to say it is the end-all be-all solution for TKO/TKX swaps, and I will be contacting Silver Sport to let them know. They were also interested in a solution but have not come up with one yet. ToddRonn told me yesterday that they sold all their stuff to Modern Driveline, so they include that crossmember in all their T-56 kits. If this works out, perhaps Silver Sport can include this unit in their kits moving forward, and help a lot of people out!
