Still working on the 53 Truck rebuild. Working on the engine now. I wanted to replace the wrist pins on the 1957 235 engine in this truck (not the original 216). I have seen on eBay wrist pin sets for sale for this engine, but the box shows the diameter to be .636. Mine are .866. Where there different size wrist pins used on different years production of the same engine? Doesn't seem likely.
