Default Missing bolts in rear end.....is this bad??

Well.. about 2 months ago i decided to upgrade my auto by installing a 4K converter and tranny cooler, I then bought mickey thompsons, becuase i knew with such a stall i would need better rubber... anyways, to make a long story short, ive been out luanching everybody i know now at the race meet ups, this car is a whole new beast, HOWEVER, i went to get my cats gutted, and while it was on the lift, i looked at my 10 bolt and notice it was missing two bolts.... can this be bad? is it from hard luanching? im kinda confused, so i need your help!!! thanks.

It could be from launching, but it's unlikely. They probably were missed when you were going over them the last time.

I would say it's serious because if the gasket lets go right there and your oil leaks out it's going to whipe out your rear. Being we don't have an oil-level indicator for the rear- you'd probably notice when it burnt up. Probably not a huge concern, but I'd fix it as soon as practical.

You could also just tell people you have a "8-bolt".

I thought the "10-bolt" and "12-bolt" designations came from the number on bolts on the ring gear?

They do. However, the GM 10-bolts all had 10 bolts in the cover also and the GM 12-bolts all had 12 bolts in the cover. May be true for the 14 bolt.

There were rears that had 12 bolts covers and 10 bolt ring gears back in the 60's. Mainly BOP's, and that made a lot of people very unhappy.
