The correct belt for an LH 253 with A/C is a 11A1090.

That was a typo. I meant to say LH 253 WITHOUT A/C.

 

AFAIK the only reason the alternator belt is different for factory A/C cars is the the fan pulley was made smaller to increase the water pump & fan speed. Some aftermarket A/C systems did the same. I used to fit A/C back in the 70s.
