Clutch and brake pedals

Has anyone ever manufactured their own clutch and brake pedals before?  I 
figure on using 1/4 steel plate which AFAIK is what the originals were made 
of.  The general idea is to copy the original design except to make the tip 
of the pedal (that has the plate on it) about an inch longer so as to enable 
me to have the car seat further back, still fully depress the pedals BUT have 
a bit more arm reach (like an inch).

Any thoughts?
