If you check out the link below it's a web site for brakes parts, it shows the two types of brake calipers fitted to the TS model, if you look up the info for each type of caliper you should be able to workout by the images which type is fitted on yours. I'm not connected in any way to this site, just bought some calipers from there.
Rather interesting quote of that site
I tried my 97 and 2000 plate to be sure !
