Sure grip pinion seal

The pinion seal on my 67 barracuda fastback is in need of changing. My rear end is a sure grip and still has the aluminum “use sure grip lube oil only” tag on the cover bolt.
I’ve done lots of pinion seals on other cars and understand the whole marking the nut/yoke/pinion and counting exposed threads as to put everything back together as it was before disassembly.
My question is, is there anything special or different a guy needs to know about changing the pinion seal on a sure grip vs a regular diff?
