a833 rear driveshaft seal...???

[DoubleDlover]

ok so i tried to look it up and got back 12 different seals.... WTF... So. The seal with the big boot on it... Which one is correct for the a833 behind a 440 in a 70 roadrunner. Meaning the part number and brand. And OfCourse one that you can still get. Thank you.

Precision brand part # 5206 is the slip yoke bushing with seal. National brand should be the same part number.

Precision brand part # is 7300s for just the seal, again National SHOULD be the same number
