Lug Nut Question

Hey everyone,
I know this is going to sound elementary but, I need some help with lug nuts. I have a 1996 Tacoma with factory alloy wheels that use an acorn style lug nut. I recently purchased a set of different factory alloys and did not realize that it does not use an acorn style nut. I do not know what the year model is for the wheels I bought. I know that they are 15x7 and have 6 spokes(3 sets of 2). Could someone tell me what type/size lug nuts I need to get?

Thanks,

Mike

 

a pic would help

 

Sorry. I guess a few pics would be helpful. The first one is of the original wheel the others are of the replacements. Any info would be greatly appreciated.

Looks like a mag lug with a washer on it. I plan on getting some the next time I get down to pic a part.

 

Thanks for the info. I now have another question. It seems there are lugs with different length shanks. What length do I need?

Thanks,

Mike
