Buy a proper SYE from Advance Adaptors. It will come with instructions. Advance Adaptors used to make the 242 SYE and Tom Woods was the exclusive seller but that exclusive agreement has ended so you can buy direct from AA now.
Or buy the factory service manual for your vehicle.
You do need a good pair of snap ring pliers. The $14-17.99 ones from Sears/Craftsman ones are OK, but the SRP2B from Snap On are better. 10 or 13 mm 12 point socket for the top bolt, and a tube of Permatex/Loctite Gray and some vasoline to hold the needles in place from Wal Mart are the only "special tools" you need.
Just be sure to keep the RTV as far away from the oil pump tabs as possible. If too much is used too close it gets under the tabs, cocks the pump and you will destroy the oil pump seal. Not just the rubber part of the seal, but the metal part will get ground out.
