Here's the 11.75" Wilwoods with a 17" rim. The biggest disadvantage to the Wilwoods is that they increase the front track by 3/8 - 1/2" per side, necessitating wheels with extra backspacing.
You'll probably hear the 11" Granada brakes mentioned also. On a 65 with modified suspension geometry, beware of the slight differences with Granada spindles - can cause bumpsteer issues...

Can't tell you for sure vs. a 70 spindle, but the ackermann is different for a 65 vs Granada. Looking at the spindles from the top, the tie rod hole is further toward the centerline of the car - that's why so many people swapping Granada's on a 65/66 car run out of adjustment threads. Also, the shorter tie rod assemblies make a poor bumpsteer curve even worse. I think there was even a thread on corner carvers about Granada's & ackerman a while back.
Everyone I've talked to with modified geometry, fat sticky tires, and Granada spindles on a 65/66 car has had problems. I'd bet that I've traded emails with 20+ people over the last several years, who were ALL chasing the same problem. Here's one going on right now.
The bumpsteer issue on 67-up cars tends to be less severe than the 65/66 cars.
