Steve Knight 1978 is #126 which I have but not as a double. Use the # also in your request as Scanlens didn't put teams in numerical order back then. Some ppl can be reluctant to sift through entire sets. I'm supposed to get my hands on a whole set from 78 soon, and if I do, I can get that card for a small outlay. keep in contact and good luck
P.S. I live 5 mins away from you so great if you want to trade in person
