72 gas tank sending unit

[72WiscSub]

I purchased a sending unit and after it was shipped I realize I might have gotten the wrong part. The unit I ordered is for a 72 pickup although the product description said "72 V8 sending unit", so I thought it was the suburban one. Anyway, will this work in my Suburban or do I need to order the panel truck specific one?

I had to have it overnighted because the tank is already out and I have to get this thing moving. I really don't want to send it back and have to overnight another one.

Any thoughts or opinions would be great.
