#1471, "RE: what are the tap specs for the GM sensors" In response to In response to 4
Well Doug is right, if you use a 9/16 you have to tap from the biginning of the tap, if you use a 37/64 you start later in the tap and makes for a little less effort. Different tool amnufacturers prolly recommend a slightly dif size. Snap on i have says to use a 9/16 but it would be a tiny bit faster if you used a 37/64.
