I only put about 50km of driving in before I checked the belts, reason being I heard a little squeak starting. The alternator belts had so much slack that I thought the tensioner gave way. You can see the slack of the belts in this picture. But look at the tensioner bolt, its getting close to max. What gives?

So I retensioned the belts and they seem tight again. But now the tension bolt is at its limit and connot be tightened anymore. Keep in mind there is still about 8mm of deflection. I'm stumped on this one.
Tightened:

I feel like the new belts are the wrong kind but they are correct as per the Delica Wiki. Dayco---11A 1105
Any help is appreciated.
Cheers all,
