Those with '69 383-440's that are running the stock A/C setup....what belts (size, part # etc) are you using for the AC/Alt?

The reason I ask this question is that I actually have tried 2 different sets of belts with the same problem....
I have the set of the Quanta repro belts since last season. I have heard horror stories of these belts stretching so in case I bought another set of Good Year replacements.
Fast forward to this season...checking the belts I felt the AC/alt belts were "looser" than last season...that & the fact that I am at the end of the adjustment on the alt bracket made me decide to swap out the repro stuff for the Good Year replacements because I knew I would be driving the car more this season (hopefully). Go to put the AC/Alt belts on & what do you know...even WORSE (looser) The belts are 61" long. Went ahead & ordered up a set of 60.5" belts...no good too short. Took the lower alt bracket off & elongated the adj slot till almost the end of the metal & finally got the belts fairly tight for my liking.
So my question was what size/type of belts are others running & do they have the same problem as me?

Thanks! Question though. i have had the Mopar belts before when I didnt have the AC set up on it. The 2 numbers before the last digit indicate the length. 13601 is a 60" belt 13441 is a 44" belt 13361 is a 36" belt.
If your A/C belt is only 60" long, then you must be running the compressor with the 5 5/8" smaller pulley (pulley is flush with the clutch) I have the larger 6 5/8" pulley so I believe those belts wont work for me. Can you confirm your a/c clutch pulley?

This is the larger clutch off my car....440's had this one mostly although I have seen the smaller one on 440's as well. 383's mostly got the smaller size
Small on left... larger on right...
