oil pump drive shaft bronze gear

I have a 408 stroker that will be running a solid roller cam.
I tried buying a Milodon Oil Pump Driveshafts 21535 assembly from both summit and jeggs only to find out that its back ordered until sometime in May or June. Of course the Mopar performance one is available for around $75 more. I know I can buy the gear separate but feel better with both new and matched. Anyone know where I can get the milodon driveshaft or is my only other option the mopar performance?
Thanks
Rod
