Best place for Repo fuel tank and 3/8 sending unit to buy from

I bought a Spectra tank and 3/8" sending unit from Summit - free shipping. My filler neck looked good from the trunk side, but when I looked inside it was badly rusted, so I got that from 521 Restorations. I ordered the pad and J-bolts from Classic Industries. It took about 2 months to get the J-bolts.
