By any chance does that a 216 have two small baffle screws in block behind gen. 2 screw 6” apart
All 216s and 235s have those screws, but they're on the passenger's side, not behind the generator. They hold a sheet metal deflector in place below the road draft tube to keep oil from being splashed up into the draft tube by the crankshaft. There's a 3-screw sheet metal plate on the driver's side, called an "oil distributor" that meters oil through a copper tube to the rocker arm shaft. Jerry

Jerry, Punch is asking about a draft/oil filler tube baffle for his "207", which he has posted about elsewhere here and in the Swap Meet.
Punch, The 216/235/261 baffles regardless of year won't fit your "207". You need to find a 207 donor unless you figure out a way to fabricate a replacement deflector.

The baffle plate needed is p/n 837998 (as posted by Dan in the Parts Wanted Ad). 1936 was the first year for the Baffle so it's a one year only part, If my memory is correct it was held in place by (2) 1/4-20 round head machine screws with nuts. One is located behind the Gen and the other just above the dip stick.
Here's a cutaway drawing showing the Baffle from "Chevrolet Six Car and Truck, by Page' ".

Excellent info and much appreciated. My truck is definitely a 1935. The description of the two mounting bolts is exactly right with a spacing of approximately 6”. Nice job.
Punch, what's the casting number on your Block? It's not uncommon to have a 1936 block in a 1935 as the 35's were prone to overheating as the water jacket didn't cover the drivers side of the cylinder jugs...they fixed that for the '36 model year and from then on used the '36 as the replacement for the '35. The '35 block didn't have the baffle plate.
1935 Block = 837591
1936 Block = 836010
My info is based on US made parts...Canadian might be different???

Punch - Your block date casting code "J298" decodes as J = October, 28 = 28th day, 8 = 1938, if the Canadian casting date codes match with US code info. The later casting date could (maybe) mean it is a replacement engine as we have found in some later year engines. Perhaps someone with more knowledge of the earlier engines has some info that might confirm or refute this info?
I can't find anywhere in your previous posts on what the engine serial number is??? Can you post more pics of your engine so we can try and better ID it?

It's actually a 1936 block that was cast in 1938 as a replacement (a 1938 engine would be a 216). The machined surface in his picture is missing a serial number, meaning the mechanic that replaced his engine didn't transfer the original engine number over to the replacement block (very common oversight).
The engine serial numbers and the body serial numbers were never the same.

Why not just make one? It's nothing but a piece of sheet metal. Jerry
