Mark,I used them,nice easy install,they cut to fit as i'm sure you're aware,the only issue I had was the left rear caliper faces the back so had to route the conduit carefully but there's plenty of extra length to allow for this,not a problem if you're using drum brakes.... see here..
I've used a Gen 3 Pontiac rear with discs,once I got the brake calipers adjusted correctly it works just fine.
Just make sure the foot pedal plate 'bites' onto the pedal shaft well.
