I have rev T in digital form but is there a 2018 version of the 818 manual??

I am starting to work on body install and have read alot of install threads but most are S versions and few Coupe versions.

In particular , I am leery to bolt top of side sails in rear without putting on roof to check width fit and also wonder if I can do front without having windshield there.

Any coupe builders or others have any comments. Hoping the 2018 version of manual may have some roof install.
