Another possible answer for end plates is to 3D print them. Doing it cheaply is not going 
to do you any good EMI wise (it’s plastic). It will keep dust and bugs out of the enclosure. 
Doing it with a metal loaded material is probably less than $7 an endplate, but not as 
good looking as the “real thing”. If anybody wants to go that way, I’ll probably have a set
of .stl’s done up soon. ( = I’ll give you the files, you do the printing). Contact off list.

There is a $100 minimum order policy at P-M, shipping and taxes additional. The end plates with gaskets and screws are $7.25 each so we'll need to order 14 end plates to meet the minimum; that's enough to do 7 enclosures. The plates are cast aluminum and are blank so you would need to drill your own holes per the diagrams Art provided.

>> The TAPR GPS Kit documentation has been updated and revised for clarity (I hope). it includes details for purchasing end plates and also dimensions required to fabricate end plates. The TAPR GPS Kit document, and a motherboard schematic for reference, is now available on Synergy's "GPS for Scholars" page:

>> Simple interface board schematics (Serial Level converters, and voltage adjustments for external antennas/ 3.3 or 5 V) can be found throughout the Internet since mid-1990s.
>> Numerous radio amateurs DIY their own (breadboard) or sold small interfaces at hamfests (1996-2006), until newer GPS solutions became surplus (and smartphones with built-in GPS appeared after 2007).
>> Doug McKinney, KC3RL (SK, December 2006) offered interface boards for the Garmin (GPS-25) and Motorola receivers until about 2005.  I have one of Doug's boards in my GPS parts box.  These were sold by TAPR until their inventory was exhausted.
