ok, this is what i found, courtesy of @skrews
dorman #42324

Auto Value : PCV Grommet - 0.720 In. ID - 1.883 In. OD - 0.535 In. Thickness Dorman - HELP

however, it looks like it was suggested for a 1 5/8th hole, which is not the same as the 1 7/16 you mentioned
so, it may be a dud, but who knows, i would double check to hole and go from there
(here is the thread, for real this tine, i forgot it to add it before)
