1994 Silverado Front Shock bolt help
 

This will be the lamest and easiest question asked today. The bolts are broke off in the holes and I need to replace them to pass inspection. Does anyone know if the thread pitch is 5/16-18? I can find a part number but the thread pitch isn't listed and I will be drilling and tapping the old bolts out. Thank you in advance for any responses.

Luckily I was able to get one of the broke bolts out. In the event anyone needs to know. These 8x1.25mm bolts. Factory bolts are pointed, but you can use a standard bolt.
