Longhorn Build

[TossingLead]

I am looking in to building a Longhorn Tucked Dually.
I've been look and putting together a list.
I have come across a 1979 1 ton Wrecker and wondering if I would have any trouble moving the front suspension, differential, and master cylinder/Booster.
From what research I have done shows it all should be able to go.
What am I missing or should look out for?
This is still early in the planning and the Wife could end it at any time.

Thank You
Jeff
