Who ever did the tune up last ended up cross threading the spark plug cylinder. Trying to find a tap big enough but need to know the pitch

17 mm ??????? NO! > Go to NAPA and buy a spark plug thread 'chaser' and try that first .. IF that don't work out, buy a spark plug thread 'repair kit' .. It'll have 'everything' you need!! .. (4.3L spark plug thread is 14mm x 125)
Pushrod got the RIGHT STUFF! Would be advisable to follow his info.......
