Don’t know if you’ve checked, but I went to fit a thicker RS rollbar to mine. Was from an RS2000 but found it was about 2-3” to narrow to fit
Mine is also mk2 based but it looks like the track has been widened and a wider Capri bar (?) Has been fitted.
Worth checking b4 you waste your money buying bars that might not fit !!
Unless you know exact what parts were fitted when it was made that is
btw, I have a set of compression struts I need to fit to mine, when I can be arsed lol
