You're fine bro & in fact I am gonna go out there in a few minutes & get an exact measurement. Plus I might of transposed em as I wrote the 2 numbers on my hand then I came in & without thinking washed my hands then saw that the numbers were barely legible. (the whole day went like that!) EDIT I got 1.532" on the snout with a mike & I cant find my snap gauges so I tried the plastic calipers again on the dampener ID & got 1&9/16 (1.5625"), the edges on the calipers ain't rounded to match the concave circular ID so that (plastic caliper)reading is inaccurate.
