Appears I have a brake fluid leak on the right rear wheel. Took off the tire to inspect, entire inside of the rim was covered in brake fluid and I noticed it looked like it was dripping directly from the brake pad. I suspect I will have to replace calipers but would like some feedback if anyone has dealt with this issue before I make the decision to purchase calipers.
You need to either rebuild it, assuming no corrosion in piston bores or replace it. Nothing unusual, very common problem. Try O ring style either way you go.
If you are mechanical to a small degree, it wouldn't hurt a bit to disassemble them to judge rebuilding on your own. It's a very simple process if the bores are not corroded (they may well be stainless steel lined already as original (un-sleeved) calipers are getting fewer and further between). If they are too damaged to easily rebuild you can reassemble and core exchange them with no loss should you end up going that route.
There are many threads here about removing and disassembling. Ask away and you'll get a lot of help.
I will just add that the caliper pictured is a Delco. I would not trade it in for an off shore caliper. If they are already sleeved, consider rebuilding them with O-ring pistons and of course O-rings. If your hoses have any age on them, replace all four of them as well. Just a tip. Break the caliper half's while they are still mounted on the car. They are difficult to open on the bench without impact wrenches. Good luck. Jerry
What type of jack do you prefer? I have a bottle jack as a backup behind the scissor jack, but needed to initially use scissor jack as the car sits to lower to get the bottle jack under.

As others have already pointed out you really need a safe jack and jack stands before getting under your car. You will also need the proper tools for bleeding the brakes if the "pump, hold, bleed" method doesn't work for you.
speaking of o-rings, thinking the small o-rings between the 2 halves, anyone know what material are they are made out of?
nitrile, viton, silicone, other material?
need to pull one of my calipers apart and don't need a complete rebuild kit.... i hope.

Given the cost of a complete seal kit, you may only be saving a few dollars buying the rings over a complete seal kit. The Raybestos kit is about $12 and you'll have everything you need if you have to go further into the caliper. Heck you can even get it through Amazon!
