Hello New to the forum. I rescued what I was told was a 1994 2500 from rusting away next to a barn. Was told the motor runs but has water in the oil. I found some numbers stamped on the cross tube under the dash but all I can make out is KAF620C the longer number above is so faded it is not ledgeable. I have check other area but cannot find anything else. Engine has a spline shaft. Need to try to verify the year. Thank you
