I don't have the blueprints and I doubt the OP does either. Put high quality parts into that PSA and shoot the hell out of it. Lowers aren't really a wear item. Like 26 Inf said, they just hold shit in place. The shit they hold are wear items, so choose higher quality parts (like the spare Colt parts you have lying around) and drive on. If the holes aren't drilled in the proper place you'll figure it out fairly quickly.
You won't have a factory Colt, and tolerance stacking maaaaaaay be an issue, but chances are you'll have a quality home-built lower that'll last you a long time.
