Rear Trailing Arm Axle Housing Bolt thread size?

[Steve M.]

Does anyone know the thread size of the 4 bolts used to attach the axle housing to the trailing arm?
I'm going to have to re-tap them to open them back to original size because I'm having the trailing arms hot-dipped galvanized. So I'll need to get a tap.
Thanks.

Can you leave the bolts in then back them out when done?

Thanks Charlie!

I could, but the hot galvanized metal would seal the bolt in the thread. You could probably break it loose. However, too late. I didn't have any extra bolts and they should be ready for pick up this coming Tuesday!
