may i make a suggestion,
I have found the gap for the strip is avearage of 5mm, the red pinstipe in halfords comes in 3mm or 5mm rolls one roll will do one car,
hoever if there is a motormainia or A1 car spares type of place near you or even an independant car shop try there first,
My local A1 spares a roll of 6mm which does fit nicely if lined up right costs £2.36
i cocked up a bit so needed another roll, halfords wa the closest place & for the exact same brand of pinstripe it was £6.99!!!! over twice the price! hence why i hate halfrauds!
every little helps!!
