Discs on an 8 3/4?

Anyone care to guide me to what kit i should be looking at? I had seen the scarebird stuff before, just never used it due to all my stuff being '73+ up. I have bbp axles now but the housing had sbp's if that makes a difference as far as the conversion kit. As you can tell im a newb when it comes to this stuff.

I think these are what he's talking about, this is their rear brake set up. 1965-72 Dodge, Plymouth "B", "C", "E" body rear disc

But, unless you've offset your springs they won't fit, that's right from the Scarebird website - "These brackets will work with 8-3/4", Dana 60 and 8-14" rear axles. Will not work with "A" bodys unless springs are moved inboard 3/4" or more and have 5 on 4-1/2" bolt pattern. This combination require 15" rims and will not fit the earlier two-piece axles."

Regardless, I think people get excited about Scarebird stuff because of how cheap the brackets are, without considering how much it will actually cost to buy all the parts you need. Be sure to figure out what ALL the parts will cost first.

Sorry, but as far as brakes go I can't say going with the cheapest kit out there is a good idea. Dr Diff's kits are definitely not the cheapest, although they're not the most expensive either. And they work with the original tapered axle bearings, while a lot of the cheaper kits require green bearings. So, if you don't have green bearings already and you buy a cheap kit that requires green bearings be prepared to spend more money on new axle bearings, plus the install if you can't do it yourself. When you're looking at rear brake kits, make sure you know what axle bearings are required, what brake hoses you'll need, and if it comes with a parking brake provision and the cables you need for the parking brake.

If buying a good kit is too expensive, you're better off staying with drums. Rear drums are good enough for a lot of street cars.
