Hello I would like to ask for your suggestion on 360 Challenge Stradale seat belt.My CS which came with the standard 3 points belt. I would like to install a 4 points belt. Which I believe that it have to change the entire rear window cover and lining. The rear window cover which I think including a holding point for the 4 points belt. Anyone ever experiencing in switching from the standard belt to 4 points belt on 360CS before? And the second question.Finally,I have attached a photo of 360cs 4 points belt and rear window cover suitable for 4 points belt for your reference.Thank you so much for your kind assistance.
