My dad quit racing 10 years ago then retired and moved to Florida, he raced Late Models since the seventies. On his last visit this
summer one of his old buddies sold him/us a
bomber. After recieving the car my father went promply back to Florida leaving me to
make sure this car runs and meets tracks
Rules. After talking to the people at the track - (I work there on occasion) I was told
I had to convert my rear drums to rotors. This is a 80's metric, I have researched Kits, they all seem to be very expensive and
far from stock. Has anyone done this with Reclaimed or Stock parts. Any help would be greatly appreciated.

Easiest way to switch to discs is to get everthing from

Get the Wilwood discs, Speedway steel rotor hats and weld-on GM metric caliper brackets. Whole deal is around $100 (if memory serves) plus metric front calipers and fittings. If you really want to go nuts, get a steel brake line kit (lines, clips, fittings and braided lines) and re-do the entire car.

Thats the easy way. I've heard you can use everything from S-10 4x4 rotors to Volvo rotors if you want to save a couple bucks, but other poeple can help you with that.

I know it would cost even more cash, but now might be a good time for you to look into switch to a 9" if legal. It will be a better, cheaper set up in the long run and the rear disc set up is very straight forward.

Hope this help somewhat.
