Thanks for the response.
The vacuum wipers were disconnected by the previous owner. Thanks for the heads-up on the dowel port use. Was wondering where they were to be connected.
Being that the engine is much newer than the truck, I wasn't sure its original oil filter configuration. The serial number on the block flat by the distributor is not there. The surface is ground flat with no paint. Thinking that may have been done during a rebuild or the install into the truck. Not sure.
If I wanted to install an oil filter, it would need the green arrow port opened up by drilling it out. Guess that will need to wait for the next rebuild.
Thanks again klhansen.
