I know it bolts right in, but do the brake lines work? What do I need to get the 98+ brakes to work?

 

If your stock lines don't work, it's not really a problem since for about $10 you can get new hard lines and attach them to the rubber lines off of the calipers and to the stock "T" that is on your car.
I had drums on my formula and put a 98 rear on the car, but my lines were all rusty with holes in them so I just bought 2 new hard lines, a long one and a short one.

 

How do you make the connection between the rubber line from the caliper and the metal line from the rear?

 

either buy the right length brake line with the fitting already on it, or flare and screw it on yourself.

 

I replaced the metal line on the rear with ones from the parts store with the fittings on them.
I then attached the metal line to the rubber hose on the 98+ Brake Caliper and then to the stock "T" fitting that is attached to teh top of the pumkin.
