1987 sender interchange

[bark]

Hello, I got my new 87 blazer 25 gallon tank mounted in the back of my 76, but am having a hard time to find a used sending unit, I heard that the 87 trucks used the same as blazer/jimmy ??? are there any other chevs that use it also, just to broden my search. I can buy a new one, but am trying to keep costs down, and thats $150 that I can use else where...

Thanks
