[Fot] Weight Reduction TR3-4

[Bud Rolofson]

Barry,

Please send me a copy of your component table. I'm in the process of  
making similar type decisions on what parts to use and what race  
category it would put me in to use certain parts. Weight  
considerations are high priority part of that process so your timing  
for me could not be better.  Thanks for sharing.
