[DreemKiller]

I've had a 56 for a long time, and am hoping to improve the stopping power. I am in the process of getting the power brakes fixed (it originally had them, but the booster hasn't been installed for at least the last 20 years), but am also thinking about converting the front brakes to discs (along with improving safety by switching to a dual cylinder master cylinder).
I was wondering if anyone had done this, and if they had any advice about the different kits that are available. Larry's and Concourse Parts have kits for about $950, and Casco has one for $1150 (or so). Does anyone know what the difference (if any) between the kits is? Price isn't the primary factor here, but I'd feel like an idiot for paying $200 more for the same thing.
