66 hipo dart info

I believe the 8 3/4 changed in 65 from the threaded axle end to the flanged axle end that we are all familiar with. The 65's also had the ball and trunion front u joint. It would be interesting to know when that got changed also. It looks like 65 was the year to try new things. The 7 1/4 was standard but wouldn't hold up to a 4 speed so it got changed in production. The 8 3/4 looks to be standard with a 4 speed in 66. I would bet the 7 1/4 was standard with a auto in 65 and 66. The 273-4 was a engine option and didn't automaticlly come with a certain transmission, rear end or brake. The brake sizes are a different story. It doesn't look like 10" brakes were standard unless you had the #368 Rally package in 66 (which also included a front sway bar, larger torsion bars, striped 14" tires {some info says red stripe and some says blue stripe} and wider rims {5 1/2"}.
Anybody know if there was a "Rally Package " available in 65?
