Well I finally acquired my very own 78 K5, and from first impressions they are awesome. Couple of questions though. This K5 is basically factory with the exception of 33 BFG's This is Zero Emissions stuff on it, not even a Cat. Had to replace the Ignition lock and it took a 1976 cylinder (78 would not fit) it has a 350, SM465, NP205 and D44 Fromt 12B rear. Qustion was is this combination normal for this year, Good note: Almost no rust, it lived it's entire life in the desert.
