I read on the old probards wecrash what size everyone used but cant seem to find it due to the downsizing of the threads already. If anyone can share any info it would be greatly appreciated

I tap mine out to 1/2". I wouldn't go any less then 7/16. I also use fine thread not course. I drill my mopar tranny's to 5/16", tap to 3/8". A 3/8" bolt has the better part of 5 tons of tensile strength in grade-5 form, a grade-8 is around 7 tons. If you have that much force tugging on your tailshaft you have bigger problems. |

We're is it being tapped? Through the housing into the shaft?

If you are drilling into a 7/16 hole already there from factory it makes most of the threads pretty useless at the end and gives it a place to break with a smaller bolt. At least that's how most gm trans are. Everyone does things there own way and does them how they want this is just my personal opinion and preference. I have used a 3/8 once on my first time drilling out and tapping. The bolt ended up breaking off just inside the yolk. Not sure if it was something i did or what happened but never used a 3/8 after that. |

A good sharp drill and tap so you don't fight it! I personally tap mine at 3/8.
