Hi thanks for the reply .
think I’ve found it. The pedal arm just slightly catches the bracket under the dash as it travels the last inch or two . Which makes the sound . I’ll just grind it away, can’t be arsed to take the metal bar all out again. My spine won’t forgive me .

can’t seem to get reverse . It’s a ib5 box with a straight cut gear set using the original rs turbo gear selector .. the gears seem really close , think the guy I bought it off said it had a different gate inside .. was a few years ago now ..as far as I know there’s no push down reverse . My other rs doesn’t have push down reverse?
