Clutch fork won't clip back in.

Looks like the Z is in the right way. If you "notch" it for starter clearance at least weld a gusset across the inside bend.
Is your reverse rod contacting the trans cross member? Maybe the tab on the trans is backwards and flipping it around will change the slot index.

Did you bend the clutch adjustment rod?

You will need the over center spring for the B&B.

I think this is kinda' sorta' what your looking for on the initial clutch adjustment......
