Does anyone have any recommendations for this? searches seem to only bring up auto coolers
i had an an earls sandwich and a cheap cooler and filter block bolted to the firewall that worked fine on an old car
from what i have been reseaching, any oil cooler kit from the states wont fit, unless its designed for the pontiac gto, and that first link says it wont fit.
i believe its becuase holden based cars run a front sump, and chevs etc run a rear sump, which cause clearance issues for these adapators
this ebay add explains it,, sort of
