I have seen them listed as correct for late 60's to late 70's 383/400/440/crate Hemis BB's and 1968 -1991 318/340/360 SB motors with A/C, but do your homework to be sure it will work for your application. Outside diameter of outer hub is 7 1/4", inner 2 hubs are slightly larger. It is 3 1/8" tall. $65. shipped in the USA.
