Yeah, the Israelis had a boatload of T...62s? regunned with M68/L7 105s and re-engined with teledyne diesels. Did they keep those for own use or sell them after re-manufacturing?
They converted T-54 and T-55s with 105mm, but T-62s kept 115mm as those were judged to be actually better performing then L7, so no conversion was needed. Another factor was that T-62s were actually only available in larger quantities after 1982 (there were less then 100 in use IIRC before 1982) when there was much less need to use captured tanks.
