Texas - A bit more checking in several Chevy Master Parts Books indicates your 1955 235 pushrod (one of those in Kevin's screenshot above) should be GM# 3836261. That number is listed with various length measurements including 10-37/64", 10-5/8" and 10-3/4" depending on which year the Chevy Master Parts Book was published.
Converting from fractional to decimal length indicates those would be 10.578125", 10.625" and 10.75" respectively.
The Filling Station lists their
AF-540 GM# 3836261 Equivalent Pushrod as "Overall length is 10-37/64"." for your 1955 235 application.
'Should be just what you need, considering your pushrods measured 10.6" overall length seen above, as that slight difference in length of these is easily taken up by the rocker arm adjuster screw assembly.
Hope this helps you get what you need.
