Hi Grumpy,
Yes, the maths you did was the same as mine. It's not possible to measure the length insitu for one of the belts because you can't get at the pulley under the engine when it's in place. If you take the engine off it becomes a bit of a guess where the pulley would be. I tried to order from one place but got tangled up with effective length and overall length and
metrics got in the way too. I did a trip to Supacheap to see if they had the belts - no luck. I've emailed a belt supplier for help. I'll keep you posted. Rodeobob thanks also for the tip. I'll see what comes back from the supplier and, if no luck, I'll do what you suggest.
