Any has evr replace big seal on the 5000TQ or 100Q rear diff. ?

The same one cost 4$ can, and the big ?  must very expensive. it s a 72 mm x 122mm conic shape.

I f ever very expensive, maybe i can make an aluminium disk 122mm outside and 92 mm inside the use a standard oil seal 92x72 mm very unexpensive...

Any has tought about that idea ?

(it s not a problem to go to machin shop)
