Spent a bit of time in the shop today. Transferred pattern to .040" aluminum sheet. Cut it out and cleaned edges.
used my bevelling jig/tool to bevel holes around control arm pivots.

Before forming a 90 I measure back 1/4" from the edge and slap a fold in the aluminum. This ends up keeping the edge firmly against the frame when riveted down and looks cleaner, without doing this the finished edge can be wavy. Clamped the sheet to the table and slapped/formed the lower 90.

The I turn the sheet and reclamp to overbend the 90, this keeps it tight to the frame.

Test fit the sheet to the frame. When I was happy with the fitment I drilled and cleco'd the lower 90.

Tomorrow just have to remove side panel, debur holes, clean swarf, and get ready for final assembly/riveting. The drivers side will be the same with the exception of the exhaust pipe hole and muffler br@cket holes.
