Putting Discs On A '68

I just picked up a '68 coupe project after regrettably selling my '66 a while back. Yet again, it has front drum brakes (Why can't I ever seem to find a car with discs already on it?!) and I'd like to put discs on it. This is just going to be a daily driver/cruiser, so no fancy stuff needed here.My only requirement is that this is all factory Mustang stuff, no swaps or parts off of 6 different car models.

I've done some research, and it seems that '68 was the year that crossed over to single piston calipers. But, from what I've read, '68 also had a drum spindle and a disc spindle, and in order to use the single piston calipers, I need '68 disc spindles. Is this correct? If so, it looks like my only option automatically becomes a '67 KH 4 piston setup, which supposedly fits fine on the '68 drum spindle.

If all the info I've received so far is correct, where is the best place to buy the KH setup from, and why? Also, the car is currently manual brakes with a C4 transmission. Is it worth upgrading to power brakes at this time?

I seem to remember the kit I ended up with on my '66 was CSRP, and it was pretty nice. I'll have to give them a call in the morning and see if they have a power brake kit compatible with a T5 swap. I ended up with a late model Tremec T5 yesterday for a steal, so that's something else I'll have to work with.

I talked to someone at CSRP, and they said with a '68, I can convert to the KH brakes with a power booster conversion, and the cable clutch conversion will clear it. They also said the kit comes with a new pedal, so I will order this kit along with the Mustang Steve cable kit, after I get done rebuilding the rear axle.
