If I were you I would be searching high and low for the other fender. 
If you decide you are willing to let the other block go I would be very interested. I dont need the internals, my block is badly cracked and is going to be expensive  to repair. I could also really use an exhaust manifold.
I dont know if you got my message but you had my private email wrong its   <!-- e --><a href="mailto:sgerot@yahoo.com">sgerot@yahoo.com</a><!-- e --> . you had an extra letter in there.
