Drum to Disc brake conversion kit.

I have a 67 Impala. I just recently purchased this kit. They were back ordered on the wheel seals, but you can pick them up at any local parts store. The rotors come with the inner and outer races already installed, so the ones that come with the inner bearings are just extras. Everything fits just fine and I couldn't be happier with my purchase. The only bad thing is I had to replace my steel brake lines because the fittings to the proportioning valves were froze up. Eventually I will have to replace the proportioning valve so I can get the right pressure to all brakes. But for now they work just fine. I have looked else where and these guys have the best price for this conversion any where.

Easy to install but not great quality.

The kit was easy to install. Fit my 65 Impala no problem. Received a bad calliper though. Wouldn't stop leaking at the banjo bolt. Tried new crush washers and a new brake hose and neither worked. Turned out the calliper was poorly machined. Had to buy a new one.
