Anyone installed a Sage EBR on an M1a?

[Montanan09]

I acquired an M1a in a sage EBR along with the factory walnut stock and want to put the rifle back to it's original configuration. Upon disassembly I discovered that there seems to be a part that was swapped in order to mount the rifle to the Sage stock, and the original Springfield part/s that were removed did not come with the gun; nor did any papers or instructions relating to the Sage stock.
Can anyone help me identify what parts I need to purchase, where to get them, and how to get some instructions about how to reverse the modifications?
Also, although it is a fantastic stock, the Sage EBR is not something I will use. Can anyone give me some tips on how to identify what model or variant it is, and also how much I should be able to sell it for? Tips on good places to list it are appreciated too.
Thanks.

You can follow instructions in reverse order. Hope this helps.

I just attached a photo of the Sage stock followed by a photo showing the part on the M1a that I want to replace with the factory part/s. Any input is appreciated.
Thanks.

You need the original operating rod guide and securing roll pin.
You will also need the front band that fits behind the gas cylinder and secures the front of the action to the USGI type wooden stock.
