At 1:47 you don't need to open those two bolts, those are bracket holders. You need to open only The bolt from middle of the pulley. And then losen The adjustment rod.
Ive had loads of belts for this car so far 1110 1100 and 1115 all too big / too small… went to manufacture standard and they provided me a belt 4inches too small! I think i need a 1105…
