i beleive the sending unit is on the bottom. My 68 was on the bottom, i think my 74 & 78 were also. No need to remove the gas tank, but you DO need to remove all the gas first.
The below is what I did on my 68 as it is still fresh in my mind, may be different for your year, but hopfully it helps a bit.
You have to start by unbolting the crossmemeber bracket that runs from side to side to the frame. (4 bolts) There should be two straps that run around the gas tank and hooks to this crossmember. you can remove the straps and unbolt this crossmemeber and drop the tank. Oh yeah, obviously the spare tire carrier has to be outa there. Not sure how the exhaust comes into play as I had already pulled mine out before I got to the gas tank. Try your best to access the sending unit without pulling all this stuff off. Although I would be curious to see if your tank sticker was still on there. Unfortunately mine wasn't.
Good luck.
Hopfully someone will chime in here with more info more specific to your vette year.
