After getting the birdcage done it was time to tackle the frame. All the stock spot welds were taken down and new welds went on all around. Tons of gussets were added to the critical places such as A-arm and engine mounts, crossbar, frame rails etc. Should be a lot more rigid now.
One real modification I did was the Guldstrand 5-link rear suspension. This required the trailing arm pockets to be widened to accept the upper trailing arms.
Stock trailing arm pocket looked like this. You can also see that the shock mounts will be relocated to inboard to get the clearance for coil overs.
First test fitting to see how much room the Guldstand set up would require.
The lower trailing arms needed new mounting tabs, so I decided to make a new backing plate for the mounts.
Tabs spot welded in.
Here you can see the lines showing how much I needed to cut out...
No turning back now.
Patching up that nasty hole. Here you can see how much wider the trailing arm pockets need to be.
And finally all smoothed out. Now there's enough room for suspension travel.
Thanks for looking.
