so here are some measurments and numbers.

right has the same number.....
That's very interesting.
GM does something with thier part numbers to denote "left" and "right", of the same part. Such as brake calipers. there is a difference between the left and right calipers, so there is a difference in the part number. And based upon the fact that you stated that the part number on both left and right calipers is the same, you may well have two right hand calipers. Just one installed on the left side. (or may be the other way 'round) IIRC part numbers on parts with a "left or right" are denoted by the last digit either being odd or even, with even being left, and odd being right. So a caliper with Pn of 1802328 would be left caliper, and the right caliper would be 18002327or9. And would probably have an "R" embossed on it.
That said, you could have spindles, rotors and calipers from a '70 Monte Carlo, and a center section, (X-member, and "A" arms) from something else.
For some reason I never did like to cobble together a suspension, for this very reason. The "what in heck is this" thing.
You will do well- once you figure out what it is- to make notes, and keep them with the car.
