Transmission Skid Plate Bolt Sizes

I was going to replace my transmission mount but after soaking the bolts I already have snapped two. So I need to get a drill bit and tap. From what I found the bolts should be 3/8 - 16. Is this correct?

Thanks

If you have them out, get a tap, and lay the tap threads along the threads of the old bolt... if it fits, its the one... its the only way I have ever done it..

For my stripped threads, I used http://www.timesert.com/
The kit was a bit pricey though

I had two of the skid plate bolts break on me also. Instead of redrilling and tapping a new hole, I hit the broken end of the bolt which broke the nut welded on the inside of the frame loose leaving a nice clean hole. Luckily, the two holes were in a spot where I could just barely get to them from another access hole on the frame. I then taped a new nut/ washer into the head of a wrench, fished it into the frame, and ran a bolt up into it. The tape held the nut/ washer in place in the wrench while I tightened the bolt down.

Not saying that's the best way to do it, but it worked for me.

Make sure when you put the new bolts in, you use anti-seize on them...
