My HDK install thread.

I got my set up from Denny a couple of weeks ago. I have it painted and ready to install in my 69 Dart drag car. Monday I was able to buy a rolling jack for my 4 post lift and it should make the install a lot easier. Looking forward to a better steering car with hopefully more weight transfer to the rear. Like Young Gun the undercoating removal before I had the lift wasn't much fun laying on my back using a heat gun, scrapers, wire brushes and wire wheels. Then cleaning all the remnants with solvent and lots of rags.

Good to see you're making the upgrade Jeff! Handling and braking on mine is MUCH better than it was. Steering is nice but still a little bit tough at slow speeds. I think that if I got rid of the spool (and had a big steering wheel too) it would be even better. My buddy noticed the difference in the increased difficulty of steering with his stock suspension changing from sure grip to spool. But it's completely tolerable to me. What spring rate are you planning on running and what length spring? I ended up with the 12" spring and 350 lb spring rate but it really needs a 300 lb for what I do IMO. The double adjustable shocks are really nice too. The one thing I don't like about the 12" spring is that the coilover WILL NOT go in without compressing the spring or separating the ball joints. That's the one caveat that bugs me. Also watch for the angularity of the bump stops to the control arms. If the arms hit the bump stops at an angle, the arm will cut right through the rubber to the metal plate it's molded over and will start cutting into the control arm. Mine did this and the arms are gouged up on both sides now and I may need to weld them up to make sure they are structurally sound again. I'm going to redesign the bump stop so that the control arm rests at a true 90 degree angle to the bump stop. Those bump stops aren't made for any impact except directly to the top of it. Any angularity will shred it. Good luck and looking forward to seeing your progress!
