1970 Cadillac Deville A-Arm Gear Box, Bent Frame

Could not speculate on a cost for body repairs, this is mostly a mechanical repair forum. It would depend on the severity of the damage, and probably be straight time labor, meaning the time that someone has into the job, is directly related to the labor price you pay. The battery would be around $150 parts and labor approximately. The brakes are going to depend on what needs to be done, and what parts need replaced. A simple reline, I would guess $200-300 per axle. You may need drums, hardware, master cylinder, etc. I would have a brake inspection and estimate formed from that.
