Need help selecting correct lugs..

[Ragu]

I'm getting a set of 2003 20" HD wheels (14mm) for my 99 Lariat 4x2 (12mm) truck.

I've heard that I can't use my 12mm acorn lugs for holding the 20" wheels on my 99' truck.
The wheel hubcenters as I understand but now which lugs to use?

So, which are the correct lugs to use for the 14mm 20" HD wheels going onto a 99' 12mm studs?

Which keyed locking lug will also work for this set up?

Thanks in advance

hmmm, are the '99 lugs different than the '01 lugs? I am using the stock acorns on my '01 Lariat

I'm told that the 99's are 12mm lugs and 2000+ are 14mm lugs.

I need to know if my 99' 12mm acorn lugs will safely hold the HD 20" wheel with the 14mm lug holes.

Anyone?

thanks in advance
