So...started assembling leaf springs, working on the pedal box, etc.,
I found interleaf spring material from Speedway Motors (Part #910-33035) it is wide enough to split in half. It seems softer than the factory stuff but much smoother than the original stuff. All my leaf springs parts have been painted with POR15 so have a very smooth surface for them to slide on. Hopefully this will make the springs more compliant and above all nice and quiet. May have to look at tube shocks as opposed to the levers but will try the levers first and convert later if they are not up to the job.
Now as this car is being converted from Automatic to 4 Speed I have an MGC pedal box which has been cleaned up and ready to use for the 4 speed conversion. I am also looking to change the braking system slightly. I am going with 1 booster for the front brakes only, using the MGC master cylinder due to volume considerations as the MGC brakes are a bit bigger than the B brakes but I am using old style B pedals - which are about 1/2" longer than the C pedals.
I have to go to a bigger pivot shaft as the C is .500" diameter shaft and the old B pedals used a .562" (9/16"
shaft. I also needed to manufacturer new spacers between the pedals. To that end I started looking around for appropriate spacer materials last night and found some! I bought up a whole whack of old misc car parts at an auction a few years ago - it included a bunch of really old hard bronze spring bushings of various sizes! Turns out there was some there with a .562" inside diameter and a really thick wall.
Not having a lathe (oh man that has to be the next purchase for my shop!) I cut down the bushings into a little over length I needed 2 at 1/2" and 1 at 1 5/8". Once cut down to appropriate lengths I went to work with an aggressive flap disc and file and got my bushings to where I want them. Today I am on the hunt for 5.5" long 9/16" bolt for the shaft and I should be all set!
On to the next!

Speedway Motors Interleaf material
Spring leafs with interleaf material laid in place
Interleaf materail a little oversized - will have to trim once clamped
Old style B pedals that I am using on the C
Extra length of old style B pedals
Bushing material cut into spacer 1/2" length
Bushings all cut and trimmed to length
Mocked up using the existing 1/2" shaft lines up beautifully
