Rear Main Seal ritter block
 

I need a rear main seal for my Stock Class Duster with a Ritter Block 340 engine. I cannot fin a part number or a seal for a Wet oil system. I did find one at Hughes Engines but it is incorrect. Any help would be appreciated.

Darren at Patterson-Elite can be reached at 316-775-7771.

He is always very helpful.

That is where I get my seals for my R3 blocks and I assume they are the same.

Thank everyone for your help.
I finally have the correct seal from Ritter.
The first one I had was the correct number the seal company The first seal was wrong one but the seal company would not admit it.
The correct number is sm 87123 from Signal company for a wet sump seal.
