The 261 was available through 1962 on Heavy Duty trucks (some say into 1963). Even though the Wikipedia says it was used on Light Duty trucks in 1962, it would be nice to see information from a GM document.
(
Note that there is incorrect information about Stovebolt "Era" engines in the Wikipedia). Was the 261 engine an option on a 1/2 ton 1962 truck, as Wikipedia states?
And, was a 3-speed overdrive transmission an option on a 1/2 ton 1962 truck?
If the answers to either or both of the above questions are "no", then there is an even better chance that you do not have a 235/261 truck bellhousing (it might be a passenger car bellhousing or ???).
Someone with an ID numbers book, or a 1962 Truck data book, or a 1962 Restoration Book (Specifications Manual) might be able to give informative answers?
