Mini tub 70 Dart??

It's pretty self explanatory and many here have done it, some of us multiple times.

Was there specific question you had?

The one thing is i'd only use RMS boxes as they are adjustable.
What are RMS boxes
I don’t really have a lot of questions but I would like to see some pics
The other thing I’m interested in is running some street drag tires
Right now I have 9 1/2 inch tires on the rear BFG T/A radials
I fear that I will have to get the street slick as my package will make over 500 hp
