Crossmember chop?

[gringoloco]

Been lurking and searching the crossmember chop posts and have a few unanswered questions.

1) What major snags are common to the process?
I have noted:
- Steering shaft interferes with upper a-arm. Appears to be pretty straightforward
- Tie rod end interferes with crossmember, is this both, or one side, and where?
- Any steering geometry issues that need to be worked out? Bump steer issues?

2) How is the cut made so as not to have to add filler material when reassembling?

3) What is being done in the back to even the stance? Blocks? Lower rear bag pressure than front? Both?

Anything else that I am not thinking of that I will be blindsided by?

Thanks -Chris
