If anyone has replaced this on a 1984 m1008 please let me know the part number. NAPA ordered one for me for a K30 and it's the wrong one. They said it should fit a 1982 thru 1986, but it's wrong. I look at all the usual suspects on line and some look close, some not, no measurements given. Great truck for plowing, but this is the last time I buy a non-standard vehicle!
