I've got some from JCW before too. Note that only the 63-64 Ramblers had 
curved glass, went back to flat glass for later models. Yeah, I'm pretty 
sure it was flat in the 65-66 Classic, but could be wrong.
I have had good luck re-lining the existing channel. Clean all the 
remnants of the old lining out first. Then get some self-adhesive felt 
sheets from a craft store. Cut it in ~1" strips, fold in half, pull the 
backing off, then work it in with a pop-sicle stick 8.5" or 11" at a 
time. Trim the excess with a sharp razor blade. Lasts a long time too -- 
I did mine years ago and they are still tight. Don't try to glue felt 
yourself, it just soaks up the glue! Don't know what kind of adhesive 
the self-stick stuff uses.

I made my own curved channel for my 63 classic more than a decade ago. I
forget dimensions, but I got it from JC Whitney (they do sell the channel,
or did, and it was good quality).
But I did NOT use mark's suggestion to insert something in the channel. Of
course as I bent it the channel would close, and I had to keep opening 
it. I
don't know why I didn't think to insert wood or aluminum in there.
I wouldn't hesitate to do it again but with 3/8" or whatever aluminum 
tapped
in there. I used a pair of blocks and a rubber hammer and tapped and fit to
the glass until it was acceptable.
