Service Schedule and Instructions

I have a 92 Sportline, and the previous lady owner (she owned the car for 28 years) lost the service book and instrution booklet.

I believe the service scheduile book is the same as a MK2, but does anyone know where I can get a Service Schedule booklet and Instruction book for either Sportline or even a 92 GTI Cabriolet with electric roof instructions etc .

I am trying to keep the car as original as possible.

Cheers
