Morris Minor Owners Club

Hi all,
Bought a new rad from Morris Minor centre B-ham & it is too wide for the cowl panel. The old rad measures 575mm from side to side, whereas the new one is 580mm. The cowl panel is also 575mm. Just wondered if anyone had encountered this problem before.
The car is a '62 948cc saloon.
Thanks.

Keep old radiator and have it re-cored. If the new radiator is reproduction they are not built to as strict tolerances.
