Am I right in thinking you can buy these in different sizes?
What have people gone for on their pulley wheels? Looking for a measurement of belt so i can get an alternator bracket/ tensioner for the alternator
knocked up. Engines a silvertop.
Thank you muchly 
i just put everything where i wanted it then put some string around it then went to the local motor factor and they sorted me one out.

As Adam said, put it all in and measure around the pulleys using something that doesn't stretch too much (length of flex). Then get to your local
motor factors and get a couple around the right length.
They are numbered as well - the number gives the number of 'ribs' then the length - do a search.

cheers lads, on it.
I spent a couple of hours in Halfords with a tape measure. Mine ended up 928mm but dependes on what size the pulleys are. 
the only prob i had is ive only got the order number that was on the belt. i dont no what car it was off.

ah well 1 of the 2 hours was spent cross refferancing the numbers in halfords little book
