TR2/3/3A H6 jet bearing seals

I pulled my rear carb jet bearing assembly to fix a weep.
I ordered Moss super dry seal kit,no pic.It came with three seals,two small square ribbed orings and the large cupped rubber bottom seal.
The kit does not come with the flat washers that are in the compete assembly to replace the cupped washers for the cork seals.
I went and checked the listing and I missed the note that the seal kit only fits the replacement super dry bearing assembly.I ordered the complete superdry assembly but I am wondering if the only differences are the cupped vs required flat washers.
I thought about flipping the cupped washers,filing the edge a little flatter for the spring, but I think I will wait.
After some more searching maybe I should have just ordered the 89 cent orings and bottom cork.
Any thoughts appreciated.

The ribbed o-ring is news to me. I used the viton o-ring with the original cupped washers without issue.

Thanks for reply Tom.That looks like that's what I should have done.I will see when part comes what the difference is in the "super dry" assembly besides the ribbed orings.Maybe the bearing id or spring length is different along with flat instead of cupped washers.
Thanks

The Moss Super Dry bearing assembly is installed and leak free.The bearing is about .040 larger id to fit the larger od ribbed or double oring seals.
