SS Leaf Springs

I called the mopar performance shop that is closing up in San Diego Ca to ask about some A-body SS springs.

He said they had a pair of used ss a body springs 50 bucks each w/ new shocks... the part # he could only get me the last 4 digits and I could not find springs that matched. The last 4 digits were "2355" anyone know what springs these might be?

Thanks!
