JDM ZC engine parts

Hi folks. I am looking for the part number or a link/site where I can research the PN for a timing belt tensioner for a 88-91 jdm ZC twin cam. I did some research at my locoal Honda parts counter, but all the different years/models I tried had different part nos. Thanks in advance,
Roger

Here's a very good DOHC ZC info site with links to other ZC sites:
