Hey Nick...
Here are a whole bunch of part numbers and stuff.
Some of it will be useless, Some will be handy...


ARP Main Studs

1 x 10 pack of 300-8364 10mm 1.25 12mm socket .700 flange 12pt nuts... $43.51
1 x 10 pack of 200-8592 10mm ID .850" OD Chamfer Washers... $12.19
10 x AM4.125-1LB studs ... $5.59 each ($55.90/set of 10)

The BLOCK is a M10x1.50 thread, where the stud will thread into. The other end of the thread is the M10x1.25, where the NUT will thread onto. Hence the 2 different thread pitches.
BTW, i have installed these and they are absolutely perfect! Zero clearance issues with the oil pan. The ARP rep told me to just use their assembly lube, thread the stud into the block until finger tight (assemble the bearing caps and crank girdle), then torque all the nuts down to 60 ft-lbs, NO MORE. Then loosen them all a few turns, and repeat. He said to torque then loosen a few times, as it polishes the threads and gives a better bite. But he definately made sure to stress NOT to exceed 60 ft-lbs of torque, and be sure to use the proper tightening sequence, per the FSM.

http://www.raretrick.com seems to carry quite a few CA products, including SAMCO CA18DET upper and lower radiator hoses as well as turbo hoses.
A bit late, but I ordered a oil pump Nissan of North America via Midway, and the part number is: 15010-35F01


Coils... Niehoff (from Advance Auto Parts) Part # WA2100 $68.99

Head studs

202-5402 here as well.
Originally I ordered the CA specific kit (202-4702 I believe) and they wouldn't even thread into the block. 202-5402 is the SR main stud kit which is the original arp setup people were using before the kit got its own part # for the CA.



Hope it Helps!

I might post this as a thread incase anyone was after this crap.
