  After cutting open the front rail where there was a small rust spot, this is what I found-more corrosion.   So I guess I have also to replace the two front frame rails.

  As of now, I planned to install a Chevrolet LS3 crate motor with T56 6speed manual
transmission.  This motor is rated at 430HP  but they now have a updated version of this motor rated at 500HP.  I waiting to complete the major bodywork before I order the motor.  Chevrolet might have a better choice in the future!

  Those slotted holes in the front cross member are for an eccentric bolt that provides about one degree of camber adjustment.  At the time,

I had access to automotive wheel alignment machine so I slotted the hole while checking the camber.  Now days, everybody is going to slotted camber plates on the top of the struts.   This was done in the mid 70's when only aluminum eccentric camber bushings were available.  Good catch!

The passenger side floor pan is being cut off.  Note a gap of about 1" is being left around all of the sides.  This should provide a much easier time of installing the new floor pan.

  I constructed a redneck sheet metal brake for making the floor pan.   Using c-claps, vise grips, steel
tubing and steel plates.  It did the job.  I made a sheet metal shape template to aid in creating the slope in the floor plan.  A narrow about 1" wide was hand bend to match the shape of the existing pan.  The
floor pan was then test fitted.  The floor pan will be trimmed and attached with cleco clips.

Got back from a trip to Japan.   More patching in the transmission tunnel.   Some were rust related and others were from the previous transmission
mounting holes.   Welding the right side floor panel in was easier than the left side as it had less corrosion.

I was delayed for couple of weeks as my air compressor broke down.   As usual. all the necessary parts had to be ordered from the Mainland.  Finally got the parts in and compressor fixed.   Sure was difficult to work without a air compressor.   Hope to get back on track now.

My Z Project has been delayed by a deal that I could not pass up on.   One of my customers had a C-Aire 7 1/2 HP two
stage compressor with 80 gallon tank.  It wasn't running because of a broken inlet valve.  The price was $500 so I said "Sure"
and load into my truck.   Had to wait for couple weeks to get the compressor head rebuilt kit.  I spent the time cleaning and
checking the parts.   The parts came in last week and I reassembled the compressor.  Everything is ready to go except the
wiring and control devices.  Should be only a weeks more before I can get back to my 240Z project!!!

 right side interior floor reinforcement
 
Waiting for magnetic starter switch for my air compressor so I decided to finish the floor reinforcement plates.  These 16 gauge
steel plates are located inside the vehicle at the bottom end the firewall and front section of each side floor panel.   They will
reinforce the floor and firewall directly above the frame rails.  The plates are about 4 inches wide about a foot long.  This should
spread the frame load over a wider area of the floor sheet metal.
