Manta Wheels & Handbook

[Lima]

Good day,

I have acquired a 1975 1900 Manta A (manual) with non-standard wheels and low-profile tyres. I intend to fit standard size wheels, as close to original appearance as possible.
Can anyone give me the standard wheel spec?

I'm also in need of a handbook for the car. Anyone know/suggest where I might find/search for one?
