Here is the trick with the manual top springs. To take them out put the top down to stretch the springs then put bolts in between the coils to hold it open. When you put the top back up the springs will just fall out... reverse this process to put them back in.... easy peasy. Making the patches for the front top rail hold downs. These are not visible so they don't need to be perfect but I am anal so they need to be almost perfect.... Simple tools and some careful shaping is all you need...
