Got the engine one on. Went to Home Depot and bought some bolts instead of the OEM ones to use because of cost (about $1.50 each). Ordered the engine plate online and opted for pick up at Town North Nissan here in Austin so luckily skipped on shipping costs. Bolts are zinc plated 10.9 grade which is overkill, but they were $3.00 for the 4 I needed. Size was M8-1.25 x 30mm, but you could save a little and go a shorter length like 20mm if you choose. Washers are 5/16 and were either galvanized or zinc coated (can't remember) and cost $.15 each. The bolt head was a 13mm. The threading when putting this on was a little difficult at first possibly due to dirt and crap built up on the threads.
As others have said, the quality of the pan is not heavy duty by any means, but it's better than nothing on there. I'll end up doing the gas tank next and using the same bolts from Home Depot.
Guy in parts department stated that the transmission case plate number is not valid in their system. Said the 2nd part of the part number wasn't correct. He did manage to pull up the engine cover and gas tank skid using the part numbers in this thread though. I'll look around and see if there is a different part number for it, but if someone knows of a different valid one, please let me know.
