I cant remember exactly, likely around 40 bucks each. You get em straight from Nissan Parts...You just need to find an 06 VIN. I did that by looking on the lot at the dealer lol.

Got my shift **** recently (Momo GTR2) and took an interior shot with the DD kit.

do steering wheel controls work with the DD conversion?

Mine don't, so I'll assume the answer is no.

There is an adapter you can buy (the shop i dealt with could get it, but not in stock) for 100bucks...
