Stock Throttle Body Hole Size

Anyone know what stock TB hole size is (or in my case was). Going to JB Weld and retune to get idle back down a little.

Thanks.

It depends on the year of the TB. Most times the holes are 4mm (.157") or 4.2mm (.165") JB Weld is not really the best solution. We weld the plates and then refinish them before re-drilling them.
