Shock relocation help

[ninjapumkin]

Hi guys
Need some advise
Vehicle:1964 Polara 500
Moser housing (sized to '67 length)
Cal-Trac springs

Thinking always 2 steps ahead.
I am currently mini-tubbing my car.
Will be purchasing the US car tool off set leaf spring kit to move springs inboard to frame rails. But my concern is the shocks after moving springs. They will be relocated 2-2 1/2" closer in than the stock location.
Will that effect shock travel?
Should I move or make new top shock mounts to compensate?
Has anyone put the shocks vertical instead of the factory angle? With the QA1 shock mount kit? That an advantage?

So many questions but didn't want to waste any ones time by it being a lot of unanswered questions.

The springs are relocated on my 65. Top shock mounts are stock.
