Good or bad deal?
By the way, the people on this site are absolutely great in terms of the wealth of knowledge. Smart, kind people with great tips.

Really there is not much to mess up. My biggest worry is always rounding off the nut on the brake line, so I make sure and use a flare wrench on it.

Once the hose is loose, there are 2 bolts that hold the caliper to the front spindle. Remove them and the caliper will lift right off. Load new pads into the new caliper and reinstall. Get new rubber brake hoses as well, old ones tend to swell inside and reduce braking capacity.
Then you get to experience the fun of bleeding Corvette brakes. Since this isn't your daily driver, I'd say to tackle the job yourself. It should be straightforward and easy to do.

IF you're REALLY unsure about working on it.......try to find a Forum member here close enough to you to give a hand. :cheers:
OR as a last resort......try to buy the parts & pay your mechanic the labor to do the job. :chevy

A couple of additional items/things to think about before you dive in...
Your 1979 Corvette is around 25 years old and spent at least part of its life in the northwestern part of the country where it tends to be wet a fair portion of the time. It would probably be a good idea to prepare for issues of rust so you should start soaking the caliper mounting bolts with a good penetrating oil (such as Kroil) several weeks before you dive in.
In addition to your current list, I would purchase the two short hard lines that run along the trailing arm from the hose to the caliper... These always seem to take a beating during disassembly and there is potential for them to be damaged beyond repair if rust is a serious issue. They are relatively inexpensive and will guarantee that you aren't slowed down if you happen to damage one of the originals.
Next, I would have several new retaining clips (the "C" shaped retainers) that secure the hoses to their frame mounts. These often rust badly and may need to be replaced... Also quite inexpensive.
You'll need two copper washers for the front caliper hoses (the rear hoses do not use them). Usually supplied with the calipers, but make sure you have them all the same.
Make sure you have GM castings... There are three "sets" of castings depending upon the year... The first two sets are better than the third, but all three are superior to the aftermarket calipers being sold in "jobber" type stores. You take your chances with anything, but the factory castings are without a doubt better quality.
Personally, I would make absolutely certain that the rotor runout is as minimal as possible... On the order of .001" runout. Easy enough to check on the front rotors... Impossible on rears unless disassembled (yes, I know, many claim it is easy to check runout with the rear rotors/spindle mounted, but GM advises otherwise). To be fair, most people don't do this... I would say that the majority take their chances. Then again, I've never had a problem with "air pumping" either.
The sleeves are stainless steel... A good quality sleeve will never rust and pit like the cast iron caliper casting. The pistons in most cases are aluminum and can corrode when exposed to the elements and brake dust/debris over time. At the very least, inspect them to make sure that they are new parts and not just on old set reinstalled. I simply use stainless steel pistons and avoid the whole problem... Of course that adds considerably to the cost.
The factory outer seal acts as a weather/debris shield. Around 1978 or so GM issued a technical buletin outlining a procedure to apply RTV silicone to the mating surfaces of the seal and caliper. Cheap insurance, but hardly anybody does it.
You can also switch to the so called "zero tolerance" pistons... People I know have had success with these and I'm told that runout is not as big an issue when using this design. Of course, the standard pistons are still aluminum (with the previously mentioned drawback), but I am told that stainless steel and titanium are also available at a premium cost. I've never been inclined to try them as a properly installed factory setup has never let me down.
That covers quite a bit, but don't get discouraged though... As I mentioned, most people are successful without much of the testing I outlined (and to be honest, I doubt many shops would do this unless you specifically asked them to... and then you'll pay for it too). Just keep in mind that you take your chances if you do decide to do it as inexpensively as possible.
Oh... Double the amount of beer that you were planning on! :)
Good luck!

How should the price compare to the mechanic's price? By the way, I asked him if they were O-ring calipers and he said "no, they're stainless steel sleeved." Not great brakes he's offering then, right?
