Hey guys, I sourced a 205 bolt ob yoke to put onto my 241 (same spline count) to allow me to use the same size 1410 U-joint on both ends of the dirveshaft.

But, I was recently informed that to do this the yoke seal needs to be changed. The original one has too small of a diameter to allow the new larger yoke to fit.

I am trying to find out what the seal part number, and mfg, I am looking for.

Anyone else ever make this swap, or know what I need here?
