Looking for a needle in the haystack (a.k.a. a 1971 half ton, 2WD with V8)

I've got a protect-o-plate that I always assumed was for my truck, come to find out it's not. So before I file it back away I thought I would give the board a shot for finding its rightful owner. (slim chance I know) The truck was originally sold in Liberal, KS so odds are it's still in the midwest. The truck in question will be a 1971 half ton, 2WD with a V8. VIN # CE141S643***
IF your VIN matches this one, give me the last three numbers and if it's a match I'll get it to you.
