I'm actually a little concerned with marlins 23 spline seal as all of the v6 trucks use a differnt seal and this one seems to be r151f specific, although i wpould love some more marlin seals. I also live in Canada and want to get the cases on and get it off my workbench.

I have found 2 part numbers with the proper dimensions.

SKF 13435

and

National Bearing 710418

Now it seems to be a bit of an adventure to track one down. I was hoping to find a new toyota seal number but i think that thats not going to happen anymore.
