Removing K-frame?
I removed the K-frame in my Dart without removing the t-bars first. Just losened the tension, removed the four bolts holding the k-frame, gave it a few wacks from the rear with a sleadgehammer. The t-bars slided out just fine when the k-frame moved forvard.
If you are reuseing the t-bars it will be a good idea to index them so you can put them back in the exakt same position again.
