building junkyard 9" brake setup info

I am wondering for all of those who tackled this how did you do the rear brakes? I want to run 4th gen brakes but am unsure how it will work when trying mount them with the different axle flanges.

Thanks,
Chas

Just answered my own question. Take a look at the link, the rotors are drilled for both bolt patterns. Looks like I don't need the 4th gen stuff.

You can use Moser 7900FM housing ends and have the axle hang out set to the 4th gen amount and use the 4th gen parts on the 9 inch.

Ok so a little on the Right Stuff ZDCRD05 - Right Stuff Ford 9'' Rear Disc Brake Conversions. The brake pads are from a 79 El Dorado and the rotors are modified 84 Corvette rotors. I am debating which route I want to go. Not sure which would be easiest. I might be just cutting down the axle tubes and re-welding. tough decision.
