If you call a repair man chances are he'll have to put in a compressor so it won't be numbers matching any more. Then, who knows what parts you can still get to keep it up to spec with the build sheet. Now, if it's made at the kalamazoo plant and had the high output CFM compressor option in a high impact color than by all means have it fixed. Some guy just paid 20k for one at Mecum last month so those things are sky rocketing.
