I just got done installing an oem brand new never installed softop with same new never installed factory hardware I purchased from a member on here. He got me everything I needed to go from hardtop only to softop. I installed everything all went smooth after the top sat in the sun a few hours. My question is on the rear bow there are 6 snaps. On my softop there are only 4. What are the other 2 snaps suppose to be used for?
