 Charlie, It looks like the critical dimension is the 0.31 air gap.  My concern is that a softer plastic will flow over time resulting in the screws loosening up.

 It looks like the angle part of the antenna is fastened to an aluminum wing rib.  The directions are not specific.  A Bakelite sheet on eBay costs $5 including shipping.  Item #: 281793575532 from China.  You might have to wait up to a month for shipping.  It is 1mm thick which converts to 0.039".  I would not sand it down.  The Bakelite could possibly contain asbestos.
