A 4 link rear has crossed my mind several times. I can build one. Just takes some time. I looked at the rear set up from RMS. But I just can't do that to Denny. HDK is a sponsor of this build. Really leaning toward the flex form springs at this point. Thanks for the Kudos on the build.
Removed the front core support brace this evening. I will be fabrication a new on tomorrow. I can see why a lot of structural rigidity can be had by removing the stock set up.
