Hello all. I need to replace the camshaft retainer bolts on my RB20DET. There are 14 retainers. 10 of them use the bolt with no threading on top (the top bolt in the picture). That part number is interchangeable with the KA cam retainer bolts.

The two rear retainers, use a bolt with a threaded portion on top to attach a splash cover. That part number is the one I cannot find. It's the the bolt on the bottom in the picture.

Update: part number is 1305859s00. Problem is, your average Nissan dealer will tell you that's not a valid number because they suck. :/ Google will show you otherwise.
