Hi All
This came off a 1970 Delta 88 but will fit on the 1965 through 1970 88 and 98 cars. It has the single piston caliper that was used in 1969-70 cars. The rotors have surface rust on them from sitting, but no grooves. They also have about 0.020" that can be turned and still be usable. The drivers side dust cover needs replaced to make the speedometer cable function, the plastic tube that goes over the cable is broken off. I missed getting them in the pictures but I have a set of new brake pads that I found in the trunk of the parts car that are included. The price is $325 plus shipping from Medford Oregon, 97501. Please review the photos and let me know if you have any questions. I'll work with the buyer to find what shipping method is the most cost effective. John
Hi Scott
The ones I have off the 1970 don't show evidence of a factory groove. I've also got a pair of rotors and calipers from a 1967 Olds 98. They look the same but have a different part number cast into them. They don't show evidence of a groove either. These are the only ones I've come across so my knowledge is limited. Here's some pictures, the first is numbers on the rotor that came with the 1970. The numbers are on the same ring as the minimum thickness.
Then here's a try at the numbers on the 1967 rotors.
Here's a couple pictures of the face of the rotors. The ones with dust covers on them came off the 1967 Olds 98
John, I am very interested, my only concern is if the spindles fit a 1966 Ninety-Eight. I am almost sure Joe P wrote (I could be wrong) that there is a difference in angles of ball joint tapers in early cars versus later ones, I am unsure if it is the uppers or lowers. Mine are perfect, and I know replacements are very pricey, so all must be taken into factor. Thanks in advance to anybody (Joe?) who could answer this! Regards, Howie.

All full size cars use the same upper and lower ball joints for 1965-1970 model years. The spindles will interchange among those years. The ball joint stud taper changed with the redesign for the 1971-1976 cars.
The only quirk in the spindles for these cars are the early (first design) 1965 Eighty Eights that used the smaller wheel bearings. This is irrelevant if one is swapping the complete spindle and disk brake assembly anyway.
Of course, the 65-66 Jetstar 88 spindles are unique in that they use the A-body wheel bearings, hubs, and smaller brakes, but the ball joints are still the same as on all 65-70 full size cars.

Joe, thank you very much! I guess this is where I mixed up things, the new -71 up versus the old -65-70 with the taper. Another question for you: Will my in good condition dust cap with the speedometer drive fit the disc brakes?
It will cost me a bundle with Canadian 'Peso' exchange and shipping, hopefully to a friend in NY State but these unicorn brake setups for the 65-70's are not parts one trips over every five feet on the street! As a note, I guess the Jetstar brakes must have been pretty marginal being as small as they are!
Sorry, but no, I sold pieces of it. Now I'm needing a setup myself! This morning there was someone on facebook that had a 1968 setup. But the caliper brackets didn't look correct to me, so I'm not positive its from a full sized Oldsmobile. If your on facebook send me a pm with your contact information and I'll send you the link so you can check it out for yourself.

That setup on FB has the brackets for the 67-68 four piston calipers. For the price, I was tempted to get it myself.
Unfortunately, while the 69-70 caliper brackets for the B/C-body cars look like the ones for the A-body cars (which are available repro), they are different part numbers. That means that you can't easily convert these 1968 spindles to use the 69-up sliding calipers. The four piston calipers for the full size cars are different from those used on the A-body cars due to the thickness of the rotor (1.25" vs 1.00"), but I believe they are available now.
Joe, I do have most of a full sized 67-68 setup. Maybe I need to check it again, but I didn't think the caliper brackets looked like the ones he had. I've also got parts of a 1967 Toronado setup. Lots of parts, but not complete setups!
