i have just taken apart thr rear beam and arms on a track car project to clean them up, now i was convinced that it was cosworth running gear, beam arms arb ect.

But i am begining to wonder if it is, firstly when i took it apart where the large plates are under the beam bushes there was an insert between the bush and the plate?? Dont remember my 3 door having this?
Secondly the drop links from the arb seem a little short, again without going into my garage to compare i aint sure but from memory they look an inch shorter.
Lastly the bushes in the arms dont look like the cossy ones acording to The Youth, just wondering if it may be xr4i , or is that totaly diferent??
