where in the world can I get a new rotor for my 1970 Olds 98 LS 455 ??

 

No one makes new ones. You can adapt replacement rotors for a 2003-2006 Cadillac CTS with some machining. See this thread.

 

This is fantastic news, I had read the post about the CTS rotors, but wasnut sure if it ever actually worked out. So all I have to do is have the center bored out on a lathe and redrill the stud holes? is there anything else that needs to be adapted for this to work? will the studs press into the rotors the same after they have been drilled out??

 

Yes, center bore and redrilled lug holes are the only changes. The rest of the rotor dimensions are close enough to work just fine. The sliding calipers accommodate the negligible differences.

 

Just being clear before I go disassembling the hub from the rotor, The wheel studs will still press in properly and I can use the factory Calipers?

 

Yes. The holes in the rotor hat are new ones that you need to have machined, so if the machining is done correctly they studs press right in. The hat thickness is close enough to not matter. You might want to consider replacing the studs to avoid potential problems with worn or distorted splines. They are available from RockAuto.

 

cant just drill the holes out??

 

Look again

 

Rotors are ordered, my buddy teaches metal shop and is gonna machine them out for us. Thank you so much

 

so next question, which cadillac cts rotor is this? I called to order and they asked which suspension CTS has, I guess there are 2 different rotors for the 03 CTS

 

Sorry, I thought the part number was in the link I posted above, but it isn't. They are the rotors for the base CTS brakes (FE1). I used Raybestos P/N 580120. There are several different versions available from Raybestos. I used the coated ones (580120FZN), but they are all the same dimensionally.

 

got them on order now $150 canadian per side, better than scrapping the car cause it wont pass a safety inspection.

 

RockAuto has them for $48 each. I don't know what that translates to delivered, however.

 

Finally got one of the rotors back from the machine shop, 2nd one comes back this week. Went well, but my goodness wheel studs are not fun to install

 

I will say that getting the new studs in and having them draw the hub tight to the rotor is posing a bit of stress for me. I have a small gap between the hub and rotor and I cant seem to get rid of.

 

You need to use a press. Support the rotor from the wheel side and press the stud in from the backside of the hub.

 

Ugh, I was hoping that would not be the answer,

 

No press required, Used 3 washers and turned the nuts backwards ( tapered edge out) and we got it all put back together now. Thank goodness now for rear shocks and patch a small hole in the floor then off to get the safety done. Car should be on the road before he gets his license in June
