Hello everyone, new guy here and wanted to chime in on this topic as I just received my stingray top on 4/14/2020. Couple of things that should be considered before buying this top. First is do you have a double DIN dash mount radio. If so, know that the bracing that goes inside the dash will not work with your unit as shipped from Twist Dynamics. The brace interferes with the radio. 2nd you can not attach the bolts to the upper brace because the radio shell interferes with the bolts.
If you have a MadStad adjustable height windshield, it is not compatible with the Stingray because there is no adapter at this time to attach the center brace for the windshield. I will likely end up hacking up the original brace and making my own brace.
Last but definitely not least the instructions that come with the unit do not accurately represent the hardware that included. Case and Point: the pictures show straight bars across the back between the roll bar attachments. Reality, the bars have 2" offset bends in them and the bars are universal so you are left guessing as to which way the offset should be placed. There are 4 possible scenarios that they can possibly be configured into and still fit. The correct answer is that the offsets go toward the back of the Slingshot. Additionally, the sequence of events do not match what is needed. The description of the hardware used is not clearly outlined. I thought about writing my own version up and selling it to them.
So if you venture down this path, know what you are getting yourself into. With luck, I will finish my tonight but will not have the center brace attached after grinding and cutting the "horse shoe" to make it at least attach to the lower dash but could not attach it to the upper brace. Hopefully, I will finish tonight.
