OEM skyline GTR upgraded front propshaft / driveline hardware

These are the front propshaft bolts and hardware Nissan should have used from the beginning!  Having dealt with rounded over and stretched hardware long enough l, we found an OEM solution. The bolts have a 60% larger surface area vs the orginal units, so that means no rounding over. 

We have used these bolts and hardware with much success and now we are stocking them for public access.  

All the hardware used is OEM Nissan.  Price is for a complete set of 4. (4-bolts, 4-lock washers, 4-flanged nuts)
