The glass will only fold horizontally if you have the top with the extra rib otherwise it will hit the roll bar. I don't have the extra rib so it wont fold horizontally.
So ya i have an unedited video on how to get to the engine with the Gahh top that i haven't gotten around to upload because of a packed schedule. So if you have the Gahh top it should fold like the pictures. I used a rod to hold the top because i did not have a bungie rope. It is a limited space but you can manage. Hope this helps. Also note you could rest the glass a little above the roll bar which can be kind of seen in the pictures.
