(3) looking for a some thread sizes off a FD
 

Hi all! what are the metric thread sizes for the following:

-lug nuts

-oil cooler return/sending lines from the engine block

many thanks!!

I think its 12x1.50, you can go to you local auto store and they usually sell lug nuts and studs and they have a book that tells you what size your car should take. Well at least thats how it is in the states.
