Hi there,

I am in the process of wanting to converty my front drum brakes to disc and would like to know what would be involved, the costs and where the best source of parts would be.

Maybe you should have posted this question in the "Wheels/Brakes/Steering/Suspension" section instead of the cooling/heating section?

Edit - I just moved it. Dave-R

If you look in the correct section you will find a link to the Mopar Action article that covers all the possibilities.

Or Google "Mopar Action" and go to their tech pages. The brake conversion article has the most hits.

There are also a couple of companies that sell conversion kits. Find their ads in any Mopar magazine. However they are VERY expensive.

Just another thought. Don't be tempted to use Viper calipers as some of the kits use unless you use 16 inch or bigger wheels.

You need spacers for most 15 inch wheels.

You need a new master cylinder (go with the Mopar Performance aluminum part unless you want the OEM look), rotors and calipers? Some calipers will mount to your drum spinble (SSBC), some will require a new spindle.

The best kit for a stock-like setup is to use the 73-76 A-body spindle and post-73 brake parts (which you can get from parts stores). You can upgrade on this kit by using 11.75" discs (1976 and later B-body)
The spindle is reproduced, and can be found at Master Power Brakes, for example. They can source al parts for a complete kit. It's never a bolt-on though, you'll have to make your own lines to the master cylinder.
The calipers are heavy single-piston pieces.

If you want to go aftermarket, SSBC has great kits that will fit under 15" wheels. I've seen one on a friend's 68 Charger, it's a very nice setup, and (much) lighter than the OEM parts.
AR Engineering also makes some bigger kits, like viper calipers on 11.75 or 13" rotors.
Doctor Dif (a resident expert on moparts) also has similar kits, with Brembo discs and calipers.

And then there's XV Motorsports (prepare your money though).

All this from around 700 bucks all the way to 3500.
