Rich,
Thanks...
The metal pedals are inexpensive replicas I bought off of eBay for $100 with shipping. They are attached with a couple of screws and nuts so I had to drill holes in each pedal.
Overall a rather easy and worthwhile modification. Attached is a thread with before and after pictures and some more information.
Good luck,
