Got it taken care of. I found post with a diameter of .8125 which is 13/16 that fits the seat tube (yeah its an odd size go figure) and the top is 7/8" which is .875 to fit the clamps. I ordered the B-17 from lickbike and it and the post should be installed on the Varsity by next weekend. Its gonna look great. I already have a B-17 on my 2006 Raleigh and I really like it. I'm getting it broken in and it feels better every ride in fact I may change it out to the Schwinn and put the new one on the Raleigh since it gets more ride time and the new saddle will break in faster than if I left it on the Schwinn which will probably not see the longer distances I ride on the Raleigh. Its gonna be cool an old steel bike and a Brooks what could be better.
