Chris Rogan @ motorspares. took a bit of messin around. the belts come in 5mm incriments so u can get it pretty close depending on how much adjustment u have on the top arm. i made mine the exact fit & had to redrill holes when i put the alloy waterpump pully on. will have to do the same again i think as i now have the ally power steering, crank & alternator ones to match (along with a lot more goodies) as its that time of year
