I've been searching for a CAT for my misses VW polo 07 1.2 65 BHP car and can't seem to find the exact serial num. 03D131701E03D178BA. I've found ones but they've got a couple letters different. Does it matter if the serial isn't exactly the same. The build and nut holes seem to match up.  Any help would be much appreciated.
