What size front wheel studs for '87?

[Newbie]

My spacers don't leave very much room for the lug nuts and I'd like to get longer ones. I looked at ARP, and they told me to find the stock size from Mazda.

Can anybody tell me the correct size of stock ones so I can add 1/2 inch to make up for the spacers?

ARP-100-7708 is the correct Summit Racing Part number. They are listed as Camaro/Firebird but they are 12MM 1.50 thread.

Is that part number already longer than stock?

Thanks

I use Moroso studs - I think the part number is 81460 - gives plenty of room. Have fun putting them in. I tried all the tricks - get 'em pressed and save yourself the misery.
