Cadillac 365 Rear Main Seal

Does anyone know if they made a neoprene style rear main seal for the Caddy 365 or is the only option the rope style one?
thanks!

 

a 2 piece rubber seal is available.

 

best gasket supplies one.

 

Here you go.....

 

Awesome thanks for the info!

 

sorry--had a sleeping baby in my lap before and was typing 1 handed. I think I actually got mine at advance or autozone. I know they have full gasket kits cheaper than most of the restoration suppliers.
