How wide fenders?

[K9Dober]

I'm currently thinking of buying a set of rims:

Rear 18" x 8.5" ET21
Front 18" x 7.5" ET26

Anyone with knowledge of how wide the fenders are to be? It's for my '75 1303.

Thanks in advance!:)

What brakes/suspension?

Based on standard wheel measurements this calculator can help you find out what fenders you will need as well as inner clearance to your struts.

I have a similar question regarding a -74 1303S. Not yet got the parts together but the setup will be stock brakes pared with 7x15 ET25 wheels. Will they stick out of stock fenders or maybe tuck inside?
