I can't vouch for the focus tensioner pulley (altho it looks the same and doesn't cost a lot anyways)but the cam idler should be right. Don't be forgetting the lower belt idler that came on (I believe) only 98's. If you need one I have a new one.
Get the part numbers for both and check with the signaturelm.com website
