TG501 Option1 Oscillator Y50 needed.

I have a TG501 with Option #1 and I need Y50 5Mhz Oscillator which is TEKTRONIX p/n 119-0262-00 or 119-0503-00. These are also used in 7xxx series plugins and other TM5xx plug ins as well. I have looked at the usual sources, including Sphere's online catalog and E-Bay as well, no luck so far. Does anyone have an extra unused part that they would be willing to sell? I would be more than happy to pay a reasonable price and shipping to anyone who might have one. I would prefer an item located in the USA, but would consider anything that is offered. I can pay through PayPal.
I have also read a couple of posts regarding this part and discussion about using some very common 10Mhz OCXO part to replace it. I am not 100% clear on how this is done, ISTR this involved using a 5V regulator to step down the 15V to 5V and rewiring the U50 divider to divide the 10Mhz down to 1 Mhz. Dennis Tillman touched on this in a post, I believe regarding a TM5xx series counter which he improved the performance of, using this method. I am not as experienced as Dennis, so what seems obvious and simple to most is somewhat more daunting to me. I would also consider this route, if I could get some more details, possibly a schematic, pictures and a BOM?

Thanks to All!
