I allways though the vauxhall nova heatercores were the same as the vauxhall astra cores which i use.
Am i wrong?
lkbnl can you post some pics of yours? or mesurements
The astra cores (fin area) mesures 190mm x 180mm
Pic of the astra core -
Ive also heard of something called an opal kadet (sp?) is that the same as an astra?
