USCT Level 2 Stiffening Kit - What modifications must be made?

[NHRoadrunner]

Having the level 2 kit from US Car Tools installed on a 1969 Plymouth RR. I know these need some minor modifications:
1. Add holes for parking brake cable on subframe connector.
2. Lengthen notches for fuel lines on subframe connectors.

What other modifications must be made that are not the two items above? Will everything else clear the new parts being added?

They don't fit the floors as well as one is led to believe so you'll be pushing down on the floors to weld them in place. I seem to recall some small tabs at the front that I ground off

I didn’t weld mine in, but not aware of anything other than the E Brake cable.

They’re useless if they’re not welded in!!

Mine are welded in, but not by me personally. Welded by Joe Sanderson may he RIP. He got a nasty rash from grinding off the undercoating. Asbestos. Ended up in ER.

not sure what the level 2 kit is, but it's all pretty straight forward

Frame connectors, torque boxes, inner fender braces, and radiator support brace. But thanks for the photo!

On the last car I did and added USCT stuff, I called and talked to, I think, the owner. What was interesting is he said they had done extensive testing on body flex before and after installing their products on a B body. Frame connectors and torque boxes made the biggest difference, inner fender braces made a little difference, radiator support not much at all. One thing that he told me that did also help tremendously was to weld solid the lower firewall to front floor pan joint, and I followed his advice on that.
