preduder

hi , i have a JDM 92 prelude Si and i need to change the timing belt and all other belts soon and the water pump,, even thought it appears and functions ok, just for good measure and peace of mind. My problem is that i cant seem to find parts like belts and specially the water pump for my stock
H22A motor, no upgrades/aftermarket just all stock oem..

I need help or tips if any other year/USDM EDM? parts like from the h23a1 is interchangeable for my h22a(no number after)..

BTW i bought a auto to manual TENSIONER kit from IRP.com for good measure
