They don't make it easy. You say Fortunately most parts are for the DPMS LR-308, but my bufferThere's definitely some major differences between the ArmaLite AR-10 and LR-308 rifles. Fortunately most of the AR .308 platform parts you will find online are made for the more popular LR-308 platform of rifles which most manufacturer's base their version of the .308 semi AR on.
Some manufacturer's will even have ArmaLite style cut receiver's but most likely be threaded for the more popular DPMS style barrel nut which requires a DPMS style barrel & BCG.
Section at least is all ArmaLite AR-10.
I'll tackle figuring out the barrel nut and BCG styles later.
