I know this is a bit of noob question, but I'm going to ask it anyway.

As far as I know my 1967 Morris 1000 is completely standard. Among other things I am going to buy, one of them is a fan belt.
Are the completely standard for the 1098 engine or do they vary depending on if you have a dynamo or alternator?
The attached picture is my engine. I'm sure that's a dynamo. Is it?
Also, thanks to helpful people on here I know my paint colour/code is Dove Grey BMC GR26.
Where do you buy your paints from? I'd like both a touch up pen and aerosol based paint.
Thank you in advance once again.
Craig.
