Hi Guys,check out our GTT Twin Bearing Idler Pulley,GTT Tensioner Pulley,GTT Tensioner Stop & Drive Belt. Very quiet ,much longer belt life & protection for your tensioner assembly& crank pulley should it snap

Yes the alternator is not dowelled to the block (how naff is that!) and relies on the bolts only, in there 'very baggy clearance holes' for position/alignment.
Best Regards Roland Gt Tuning.
