yes they are the same size as standard rad just not angled,i always thought this was to allow bonnet to close due to ribs underneath that would hit if rad had 90 degree corners, ive never tried to measure though.motor never overheats even when pushed hard but as soon as i come to a stop then needle goes straight to hot so maybe something else is going on?also if someone has put in one of these rads i would like to hear if you had clearance issues.thanks
