There were different sizes/lengths of push rods (pushrods) used in 235 engines between 1941 and 1962.

I think that there were different sizes of push rods in some car 235s vs truck 235s in the same year.

The Master Parts Catalog probably shows the different push rod lengths. Here is a catalog on-line that covers a lot of years.
