SOS - New Oil Pan

[Gameparker@cs.com]

Group,
in an effort to get my TR6 leak-free, close scrutiny of my oil pan revealed 
"bumps" around the holes.  Where can I purchase a non-aluminum pan (really 
means:  inexpensive) original pan either new or in excellent condition used?  
Can 
I somehow salvage my old one (machining)??
With thanks,
Geoff Parker
