Help with 80-85 Cadillac Rear Disc

[aboyer]

I am currently switching my 68 chevy from rear drum to disc. I am almost completed with the project, but I have not been able to source out the springs and levers for the 80-85 rear disc from Cadillac Seville.

I have got some GM part numbers from various sites, but when i called GM, I found out they were all obsolete. I am in need for the levers/spring and any other items that I would need on the rear parking brake calipers.

I would like to keep the parking brake option, I would also NOT like to get these items from a junk yard. Let me know if you guys have any ideas.
