They changed the sender units when they made major changes to the instrument panels and gauges. The sender unit has to be matched to the gauge -- engine doesn't matter. !973-1978 is 513321, for example, but it changed in 1979. I think it changed again by 1987.
This page says the correct unit for the 1988 is a GM #8993146:

It looks like it has the blade connector.
You can find them on ebay.

Hope that's the right one, but it is the one listed in the parts book on-line.
