Well, I bought some project kics spacers for my car and found out that they are the wrong thread pitch.. they are for a g35.. infinity nissan.. So my problem is that the adapter bolts that bolt the spacer to the hub are not the right size... Does anyone know where I can purchase these bolts in the proper lexus thread pitch? they are 20mm and 15mm spacers .. the 15s have a strange bolt with 4 holes in it for a key to fit in .. the rear 20's have a normal looking bolt.. direct me to a proper place PLEASE!

Thanks in advance
