Thanks guys!!
Made some progress on the IRS.
Welded the open ends of the x-member to the framerails, made gussets to the "diff hanger" and welded it all. That's ready!
All open ends closed like this:
"Diff hanger" also ready:
Hanged the diff in it's place and made the front and rear tie bar.
Tie bars from 1/4" steel plate:
Front tie bar, this has to take the torque bars at the sides.
Rear tie bar, ready.
An overview, just because I like it
Next on the list is to make the Torque bars and the Radius rods. The last ones need an extra x-member at about 3 foot in front of the IRS.
We'll see how that's gonna work out, unfortunately there is also a driveshaft in front of that same IRS
