I decided my earlier thread got a bit tired so for anyone interested, here are some numbers I've come up with from Spydercars and a shipping agent.
Chassis alone (original style) is 1595
Chassis with sundries, suspension, sills etc. is about 3100
Shipping port to port is estimated to be about 900

At this point I don't know how much of the sundries I will need but assuming I need all, the total looks like a bit under $5000 at today's exchange. Not cheap but I think it will add that much to the value of the car. I have not placed an order as yet and will do a very serious inspection of the original chassis before I do but at this point, I'm leaning heavily toward the new chassis rather than repairing original.
