It's located right above the oil filter, on the block. You'll need the 1 3/16 socket for it, or some other large tool. If I recall, the cost on a new one is about $25-30. It's bee awhile since I replaced mine...

Where can I get a sending unit?

 

you can get these sending units at autozone for $25. don't bother getting one at a recycling yard, you'll get a lot more mileage out of a new sending unit.

Actually, in '87, I believe that the oil pressure gauge sending unit is located at the rear of the block, below the distributor. The sender above the oil filter is an oil pressure switch, used in parallel with the fuel pump relay, to operate the fuel pump. I'm not sure what year GM combined the oil pressure sending unit with the fuel pump switch.

Yep, it's right below the intake manifold in the back closer to the drivers side... I think it's around $15

 

Where would it be on a 88 305 TBI?

 

prolly the same spot. no guarantee...

The one in the block was used for the fuel pump switch in the later years.
