two link ???

I have seen alot of two links on rangers .  I assume you set  diff angle at ride hight  and keep the axle centered with some type of panhard.  I was thinking about a  two link on my truck  do you weld the u bolt plate or the flip kit brakets or do you put a bolt  like  a leaf spring  and what wall thickness of 2x2 to use and would this be a better setup then bags on a mono leaf both would be short term. 
Also has anyone glassed a ranger dash  can i just resson the foam  or do i need to felt it first or  do I have to take the foam off.
Sorry for the spelling and thanks in advance. 

cant speak so much for for guys. but im running a 2 link on my dually with just a cross bar between the 2 links. i ran 2x2x1/4. i set my angle at 3 degrees down at ride height. af for mounting it i just used u bolts kinda like how the leafs were mounted. hope that helps a bit.   josh

thanks u catch the front hanger

if you use 2x2 make it quarter inch heres a link show how its done this is an s10 but same concept http://www.silverstarcustoms.com/gallery/view_album.php?set_albumName=s102link oh and yeah set the angle at ride height

i ran mine off the front hanger. i heard its alot different on a minitruck thow.(u need longer bars) mines on a 07 gmc cew cab dually. i always set ride height at 3 degrees down and my bars parallel to the ground. yea use only 1/4 inch thick bars. im going along the top of mine with a long gussette just to be safe. i should have used 2x3x1/4 but our metal supplier didnt have it.   josh
