What filter kit is recommended for the 34 six cylinder? What are the connection point to the engine?
Go to www.ply33.com (Tod Fitch's website) and look under Group 10 for the oil filter and bracket you need.
I do not know the location of the oil lines for your engine.
Do you have a cannister with a removable top ? The replaceable insert is I believe Fram C134PL
Do you have a filter or filter housing or are you looking to acquire one?
In 1933 and, I think, 1934 the only factory oil filter was a disposable canister. While they disappeared from the mainstream auto supply chain a while back you can still get them from some specialty suppliers. See https://www.robertsmotorparts.com/oil-filter-throw-away-sealed-cartridge-1
This is a bypass filtering system with the typical failure mode being that a full filter simply stops cleaning the oil. This means that you only need to replace the filter every 10,000 miles or so when it gets full as the failure mode is pretty benign. This is quite different from a newer full flow filter where the failure mode is to dump all the accumulated gunk into the engine if it clogs (which is why you should change the filter on a new car every time you change the oil). A $50 filter is not a huge expense when amortized over 10,000 or so miles, so just buy the correct filter and don't worry about updating things to something newer.
Regarding plumping the filter in: The input to the filter is from the main oil gallery that runs along the drive side of the block. Look for some pipe plugs spaced where the main bearings are. The rear one probably has the line to your oil pressure gauge. The one in front of that is typically where the fitting goes for the input to the oil filter.
On the return line, from late 1933 onward there is a place on the boss that holds the oil pressure relief valve. The relief valve has multiple functions one of which is to stop flow through the bypass filter is the oil pressure drops too low. If you have an early or mid-year 1933 engine in your car things are a bit different.
There are illustrations that show the plumbing of the oil filter in every Plymouth factory service manual from the first in 1934 through the end of the use of this engine in the late 1950s. If you don't have one, I strongly suggest you get a factory service manual. The early ones are more specific to your car but the later ones are more likely to have torque specifications, etc. that are useful.
