Re: REFLECTOR: Update on Seat Foam

["James F. Agnew" <Jim_Agnew@ibm.net>]

John, I had them set up for the standard seats so you will have to show them where and
how much width to take out.  Sorry I didn't get back sooner but got home from Turkey
at 2 am this morning.

I'm going to suggest that you go for the PIN Cored cushions to reduce weight
especially if you intend to use the 130-150# foam on the bottom.  They just drill the
foam with evenly spaced holes and Lee says that it makes little difference in
durability but does reduce weight.
