there was a monte carlo kit made for the pre-facelift which had arch extensions (got a pic somewhere, i suspect these were made by haselback as the same arches can be seen on the starlets of the same year) that looked awesome but ive never found any in all the years ive been looking and ive been looking a few, i have test fitted golf arches and they could be easily made to fit, xr2i (old shape) could also easily be modified to fit (tried that too)
super s ones are ok but i hardly say the make the arch look bigger arch covers more like lol
