Slap, I think there pretty much has to be.
The XF-86 was first flown Oct. 1, 1947. In December, North American leased the Downey plant to build the T-28 trainer and a few other models. The T-28's first flight was September 24, 1949.
So, when they were building the F-86, they were designing the T-28. No doubt there was some crossover of people so that some worked on both and there's always a tendency to use "off the shelf" stuff that will work.
