The one thing I will add here is that with GM motors, for a little while GM used two different crankshafts. One for auto and one for stick. A pilot bearing can be installed in either crank but the back of the crank was machined at two different sizes. I have come across this more often with early small block chevys, never with a 235. Not sure if the 230-292 motors ever had that difference but its no problem though as pilot bushings are made for both size holes. Order the standard bushing. It should require a good bit of press to install it. If it just slides or pushes in, you need the larger bearing.
In terms of material for the pilot bushing, the cheap auto part bushings are frequently steel or some other ferrous material. Run away. Other inexpensive versions are bronze but just plain old bronze. Hold out for a real Oilite bushing. I am pretty sure I have this right, the Oilite material was developed back in the 30s and remains the gold standard for pilot bushing material for our old motors. It is an oil impregnated sintered bronze. It oozes oil and lubricates the input shaft tip. Do not grease the inside of this bearing. Do not grease the tip of the input shaft. You seal up the pores and it wont ooze oil as it should. I make it a point to obtain the real McCoy and over 40 years later, no pilot bushing failures, and I am not easy on my motors or transmissions.
Other then that, I think you are good to go!
