Part 4:
Assembled front suspension, rear tranny mount and suspension.

Since the last installment, the front suspension has been fully welded and the dual-rate fox shocks bolted to the front end.
Instead of VW style tie rods, stronger steel radius rods with heim joints were chosen.  To accommodate the angles involved, some home-made misalignment spacers were made. Basically, we turned down some heavy-wall tubing in the lathe to fit inside the heim joint and allow for more movement.
This is the rack and it has some high-mis spacers on it, too.
Now, onto finishing the rear suspension.  This has been our best friend (well, our best friend who does not bring beer) during the project.  It's a Miller 135 MIG welder.  A very capable 120volt machine for most of the welding needed to fabricate a sandrail.

Since the trailing arms were installed a while ago, now it is time to mock-up the tranny mount.  Here's the 002 transmission with axles and CV's set in the car.  Once everything is square and level we'll begin welding it in place.
Here's Mike using the cheap-o Harbor Freight tubing notcher.  If you are not going to do a ton of production and are willing to spend a minute or two with a grinder to make things fit perfectly, this notcher will work fine.
This is the rear trailing arm showing the disc brakes, bolt-in billet hubs, stub axles, 930 cv's and gear-one axles.
Here's baldy tacking in the rear bars. After everything is tack welded, the transaxle will be removed and the welding completed.
The nearly finished tranny mount.
Next are the upper shock mounts. After a bunch of sketches and design ideas to determine optimum spring angles and trailing arm droop and travel,  it was decided that the shocks will be mounted directly to the rear post.  With the addition of a gusset to the top mounting brackets, the suspension loads will all push on triangulated frame members.
