i think the larger yokes were used in big block and large body cars.



correct.

my 67 8 3/4 polara has the large 1330 yoke and was only on 426/440HP cars.

I have stomped on many small 7260 yokes/joints from cars to 4x4 and never had any break..u-joints wear out and fail but never broke a yoke.

unless you are high HP with sticky tires your good to go.IMHO.
