Dang U-bolts!

Be sure you get the type with the knurled flattened portion in the middle of the U

Without that you will crush the housing tube. Also the torque is 45 lbs not 100, not that feels about right.

Look in the FSM to verify the number but I'm 98% sure.

EXACTLY! Leave the impact gun stored away.

I use a hot wrench on u-bolt nuts

PLEASE tell us where you got the flat top ones. Did they have the cross hatch on the flats? Thanks.

I just bought a set from mancini last week and yes they do have the cross hatch on the flats. Look identical to the originals.

They pop up on ebay from time to time.
Yes.

Because they don't know. How many guys do you see on here asking why something effed up and they don't even have a service manual? They don't know, so they assume and end up in trouble.

And service manuals are free. I had never touched a 4 speed before, but with a Factory Service manual and a How To article from a Mopar Muscle Magazine, I rebuilt the used 4 speed I bought when converting from an automatic. I have used my manual a lot.

I would not reuse the ubolts again even if you can cut or split the nuts. The threads are rusted and when you run die over them a good amount of the threads will be made of rust.

I find it hilarious also all this arguing about flat VS round U bolts. Here's a shocker. Mopar Performance offered U bolts. Factory Chrysler high performance parts. In their racing parts catalogs. For decades. They still offer them. Mancini sells them. Guess what? They're ROUND!

I'm in the process of changing all the bolts in my car to flat.
