Try to search couple of chopshops that do usdm and continental parts
located on the stretch of jalan kapar (nearby the BATA shoe factory), Klang.
in terms of direction, it's quite hard for me to direct here, u can just
do a google.map search (better if u got GPS satnav to guide u) on jalan kapar and go walk-about there to search.
P/s: last time spotted at least 3~4 altezza half-cut within some of those chopshops.
