I just picked up a new fuel tank sending unit for my (non-Imperial) 1960 Chrysler New Yorker on ebay. Cost me $71 bux including shipping. The seller is atwaterkentakmfg@xxxxxxx
Never did biz with him before - so dk how reliable he is or how good his merchandise is - but it wouldn't hurt to check with him, I guess.
