Bsst way to do frint suspension.

I'm not wanting to lay it out per say, but want it in the weeds for sure. I will be bagging front and rear and was curious if it's possible with spindles and a bag only? What modifications do I need to do to the control arms? Ive read tons of build threads on here but none are detailed as in specs and measurements.

Also, I plan to tow with this truck. Probably 6k pounds worth. What's a good bag?
