Torque tube seal purchase recommendation

[roadmaster_56]

I’ve got a follow up question to the replacement of the torque tube spline shaft seal for my ’50 Super w/Dynaflow.

 

Has the original design of the spline shaft seal been updated/improved for better sealing and durability?

If so:
1. Who has the best quality seal?
2. Who do recommend purchasing from Fatsco, Bob’s Automobilia, CARS,  or another source?

Thanks

I got mine at CARS.  Three in total.  All worked fine. I buggered up one.  I recommend using guide pins as shown in the repair manual. I learned the hard way by not using the guide pins.  The reason I purchased a third seal. Live and learn.
