500 kHz and 8250 kHz crystals needed

I am probably going to need a new 500 kHz crystal for my Collins 75A-1 receiver.  Obtained a "project" 75A-1 a few days ago which finishes my re-creation of all my primary stations from from the day I was first licensed on 15 May 1959.  The crystal filter in the receiver is really "screwed up" and I suspect the crystal.  I am going to take it apart and clean it but that doesn't always "fix" the problem.  Of course I would preferably like the original style.  However, since the crystal is hidden inside the shield assembly for the phasing controls I can use an HC6/U or similar type.

Also need the 20-meter heterodyne crystal.  Both the heterodyne crystals for the 11-meter (26.0 MHz to 28.0 MHz) and the 20-meter band (14.0 MHz to 15.0 MHz) were defective.  I found a crystal that works for the 11-meter band but the only crystal that I have which is anywhere near the 8250 kHz puts the band 100 kHz "off".

I know that I can order crystals from places like International Crystal.  However, being that I am a firm believer in the conservation of my finances and labor (you can read "cheap and lazy"), I am seeking alternate sources first.
