1968 Dart sudden rear end noise.

I NEVER abuse my cars or beat on them. Never tried peeling out in them. I want them to last and I enjoy driving them.
Ok gotcha.
I'm a Mechanic by trade.
I build my own stuff and I do beat the chit out of it, then fix it when it breaks then beat the chit out of it some more, until something else breaks. I did that for five years and then finally got everything strong enough, that nothing after that broke any more, lol, Then I drove it for over 100,000 miles with no more breakage. Well except for clutch discs, and tires, lol
Oh yeah and mychit peals out in three gears to 85 mph and more.
If you want my recipe, just PM me, lol.
If you want a ride, come with an empty stomach.
