I am considering buying a 1965 Oldsmobile Jetstar 88 and using it as a summer daily driver. Due to safety, I would want to update the vehicle to a dual circuit brake system and disc brakes in the front. From the research I have done (and info from Scarebird Brakes), the Jetstar 88 has an intermediate (A-body) brake system and unique front spindles, which is why I have not been able to find a bolt-on disc brake system for this car.

Questions I am throwing out to the forum:

1. Has anyone on the forum updated their Jetstar to front disc brakes? How did you do it?
2. Could I swap on front spindles from a '65/'66 Delta 88 or Chevy Impala and then put a kit made for those cars on this Jetstar? I seems logical to me, but I have not compared the parts side by side to make sure the geometry is the same between the Chevy and Olds. I'm sure the Delta parts would go on without a problem.

Any information is appreciated. Thanks!

No it isn't. That appears to be thread from 2007 about swapping a 455 into an '80
Cutlass.

 

Sorry, but you are not correct. The 65-66 J88 uses spindles that are unique to that car. Nothing else interchanges. These spindles DO use the same wheel bearings as the A-body, but you cannot simply bolt A-body caliper brackets to them.
