I went with a QT in 2010. Bought the offset dowels, farted around for 2 days. Gave up and put the factory dowels in and threw it together. Used the factory dowels with my current engine and have had ZERO problems in either. And I do run the snot out of it regularly.
An old Mopar guru told me if the tranny installs easily, forget about it. The 833's are very forgiving. Basically, if it goes in, it'll be fine. :rofl:
Just my experience. Yours may differ
