late model rear ends

I know this has been covered in the past, but I need a couple questions answered. I have a rear end out of a 1995 impala police ar. I checked through the posi unit and installed 3:42 gears. I had this installed in my '73 so I am familiar with the different size bolts and bushings. My question is with drilling the axles for 4 3/4" bolt patterns. If I pull the axles and have them drilled, what do I do with the rotors? They fit over the studs if I remember correctly. Also how does the parking brake connect up? I have the rear cables from the impala but I dont think I ever figured out how to make these work together?
I am thinking of sticking this in my '74 over the winter as it is just sitting since I got rid of the '73.

Maybe camaro rotors will work?

On my laguna I have a 95 Impala rear end but its 5 on 5 bolt pattern. The E break is inside the rotor like a inside the hat area. I have the cables coming out but not hooked up yet to the cables that were stock from the 74 itself.

I used this kit to put in all new shoes for E break.

There's a guy on here that used the stock impala cables and then finaggled something where the factory cable hooks to the rear cables. The rotors...just match up a 4.75 bolt pattern to the rotors and drill. They don't need the precision that the axles do since they're hub centric on the axle and also clamped down between the wheel. The ones I drill usually have less than an 1.8 inch of play on the stud but are still centered due to the hub.

Camaro rotors will NOT work because they have an external E brake.

So at least for the rotors; they need to be drilled also. And if I ever have to change rotors I will have to drill them again.

Now I just need to figure out exactly how to hook up the e brake cables and I am all set.

That's correct on the rotors, doesn't take much time since the accuracy doesn't have to be there...plus...how often do you change rear rotors? His suggestion was to get the rear cables, that way you have the rectangle attachment to the parking brake and then weld or use cable clamps to attach them to the factory stuff.

I will have to look into this. What are the chances of me doing this myself? Drill the axles, that is. Maybe clamp a rim over the axles with the studs removed to get the pattern? Just hate to have to pull the axles again.

Or....find a set of 89-90 Caprice only axles. They're 30 spline and 4.75 bolt pattern. New they're $100 a piece from various vendors. That's probably the best and cheapest way, machine shops may or may not want more. Other alternative is using a tool I bought a while ago. You can rent it from me for $30 and leave the axles in to drill or buy one from the guy for $108. Oh, or try using a drum if you knock the studs out. You need to make a template with something hub centric.

Could you use one of these and put it on the 5x5 stud and then mark your 4x3/4 holes to drill them?

Yes please on that pattern thing. What is it called and where can I get one?

Here's the PM I dug up from the guy who helped me with the parking brake issue...

As for the brake cables when you get the impala rearend try to.get the e brake cables too it just saves time. What you do is you heat up the end where that fitting is that clips into you frame rails and twist the end off you old brake cables. After you do that measure out the impala brake cables and cut each one so that they will go to the factory location of your car. After you have them cut you take that metal piece and twist it back onto the new cable u just cut. What I like to do is take the actual cable and pull it into the plastic covering a bit so that its not affected by the heat or cutting until I get the metal end mounts installed. After I have the cables in the car I go ahead and cut the actual cable inside the plastic sheath to length. Then after your ready to install them buy 2 cable stops ,barrel nut, from any automotive store.adjust them and you will have an amazing set of brakes. An I guarantee you will feel a difference. And on the factory proportioning valve I drove around with the original for about 6 months before I chmged it and didn't have any problems but if you plan on going racing soon I would change it out before then

Really handy if you are buying rims from some one also.

Oh, hey, it's you who gave me all that info about the Impala rear axle...haha This is the guy who slipped an Impala disc brake rear end under his car and hooked up the e-brake cables.
