I am currently thinking about replacing my rotors (still on the originals) and I noticed that I have plastic (gray) spacers on the rear wheels that are about 3/4".
When shopping for rotors, I don't see measurements and I would like to keep that "offset".
Unless I'm wrong, I don't think its original equipement, so how do I go about to keep that offset when shopping for rotors?

Its sounds to me that you have after market wheels which have a larger offset or backspacing than original requiring the spacers. Replacing your rotors shouldn't have any affect on current wheel setup.
Oh boy! Did I say 3/4 ?? 
I meant 1/4. I just found the exact same on ebay; they say it's 5/16.
Here's a pic of mine.
My wheels are rally 15/8 repro bought on ebay by the PO.
I guess he added the spacers so the back wheels stick out by 1/4" more (wait..., way more than that... by 5/16).

I'd get rid of them, myself, unless you NEED them to keep the rims from hitting the calipers. Those things are just an accident waiting to happen. I've seen too many rims fall off the cars with those spacers because they really don't allow the nuts to be tightened properly. Definitely NOT needed with Rally rims.

To Joel's comment, I say , "Right On". Things can happen. According to one of our members in Texas (was it?) there are different types of spacers. Your style should really use extended studs, but a nightmare to replace. ......A toss of the dice my friend. you may never have any problem.

I think you guys couldn't be more one the money with your advise. The lug nuts in the back were shorter (kind of just plain 'ol bolts...) and it still was a tight fit.
I'm currently shopping for rotors; so by default those spacers will be gone.
I will probably miss the look of the tires stickin' out 1/4" more, but I won't jeopardize safety for that!
And yeah; I guess I'll be ordering a set of lug nuts too!

The Chevell/Monte Carlo ralley wheels ahd different back spacing than
Corvette wheels, and are more often seen at swap meets and on
eBay. Maybe you just have the wrong wheels.
That is great information.
All I know right now, is that my calipers & rotors are standard and that the wheels were purchase on ebay.
So, before ordering rotors; if I just measure the inside of the wheels and all 4 come up the same, then it is safe to assume that the PO installed those spacers just for the look and I can order rotors without worring about replacing wheels as well?

UH, Yup. It's Twu. In a worst case, you may still need the spacers if those wheels are in fact after market and have an inadequate backset, but the rotors won't affect anything. Order away.The clearance issues are the E-brake cable and the rear spring. The cable can be pulled in and anchored and the spring can be replaced with a custom shorty. Look around and see what your up against. Rotors will be machined to an exact thickness and will not vary.
