Am not sure specifically but you can try asking at any A/C repair shops or if you have any doubt you can pay me a visit here in plaridel Bulacan so i can assist you with YOKOHAMA and it's cover. I'ts just 30 min drive from Balintawak.
When i bought my Yokohama it has a price of 12k (2008) and last year they dropped the price to almost half, so its cheaper now but i forgot the exact cost.
For the custom cover, i spent 6kpesos.
If you like, visit me first and have a look in my L300's A/C before u modify yours and then from there u can decide.
