John L, Here is the NAPA pert number for the oil pan drain kit. 704-1060. This is for what looks like an 11/16th nut and a 7/16" bolt hole, and a 1/4" plug screw. Price was $4.49. ---------Dan Nees--------- [email protected] 2 1979 Scout II's and one 1971 Scout 810 http://members.tripod.com/~IHCaholic/scoutindex.html
