... Also, it looks like both springs are the same in the picture. I ordered maybe 4-5 different springs, but I don't have any that look the same as in the picture. I do have pairs and will look at using the first ones again.
John - A quick peek into the 1929-54 Chevy Master Parts Book shows both the clutch pedal and brake pedal return springs are the same aminal. GM# 368244 - Spring, 26 coil, 3-5/16" long free length (Clutch Parts Group# 0.844 & Brake Parts Group# 4.655). I think IIRC you had a picture with at least one of those new (reproduction) with the sticker still on it previously posted.
On the Z-bracket, you could always trim a little off on the lower inner corner to allow it to lean over a little like in the VCCA picture. Wouldn't need to trim much as it only needs to move a few degrees off vertical.
Looking forward to seeing what you end up with.
