I got everything cleaned, painted, mounted up. Looks like the axles I have need to turned down, or I can grind out the ID of the rotors so I can get the rotors to fit. Everything looks great except I'm having trouble finding info on how to do the ebrake.

The left side looks fine, I can fab a bracket to pull the lever towards the front no problem.

The right side lever pulls to the rear, so i'm not sure how to do this.

Anyone got any ideas?

you need to loop a cable around the back of the rear end housing like GM did on the F bodies and B bodies that had a similar setup. get rid of the stock Chevelle cable that goes under the rear of the trans and run it all down the passenger side, then loop the passenger side one behind the rear end housing. look under a 98-02 F body or 94-96 Caprice to see how they did it, it is quite elegant, actually.
as for the rotors not fitting over the axles, i'd like GM did and get the axle itself turned down. that way, when you have to replace a rotor down the road, you don't need to gt anything machined.
