Hardtop fitting instructions for SL107 please???

[shmooauto]

Hello,

I'm collecting a rather nice 280SL ('81 model) at the weekend that I've taken as a part exchange. It's got a hardtop with it, but the current owner has never bothered fitting it. As he won't be much use in helping me get it on the car, and I've never fitted one either........ can anyone help with instructions and tips to try and make the process easier please??

Thanks,

Ed
