Correct Bolt for HRA Garand #57818xx?

Which 0f the following bolts (possibly either?) would be correct for an HRA #57818xx?

"D6528287 HRA .U." or "6528287 HRA .U."?

Thanks for any input.

65 code with no "D" prefix

Thanks John.
The rifle originally came from the CMP as an exceptionally nice Service Grade in 2003. It appears all correct (and looks original) except the trigger group (6528290SA), the stock which has a circle serif "P" and a small ordnance stamp on the bottom of the pistol grip (no DAS stamp), and the "D" bolt.
I was told at one point that it was possible (if not probable) that it may actually original as I guess HRA was scrounging for/borrowing parts at the end of their production, and the earlier bolt and SA bits may be OK. I've been reluctant to change anything because of that.
I have the corrrect HRA parts, but may just hang on to them for the time being rather than change them.
If anyone has any thoughts on the mixed parts scenario I described, I would very much appreciate hearing them.

I guess it is possible that an older "D" bolt could have been used but how would you ever prove it was original to the rifle ?? If the "D" bolt or other SA parts turned up on a brand new unused HRA rifle, then maybe, but on a service grade with other switched parts, I would doubt it and, if buying the rifle, I would be looking for a non "D" 65 bolt along with other, known to be correct, HRA parts for a 5.7 mil rifle. I don't know that HRA was "scrounging" for parts. Scott Duff states in substance, in an article in the GCA Journal, that it is believed that the contract given to HRA in Aug. 1956 for 400 rifles (6034330 through 6034729), was a "clean up" order to allow H&R to use up receivers and other components.

Joe,
Thanks for your input regarding the HRA parts. I completely agree that the scenario I put forth is highly unlikely, and virtually impossible to prove. Based on the info I'd been given regarding that possibility, I was mostly just curious. As I mentioned, although I have the "correct" parts, I'm leaving it "as is", and do not plan to sell it. I like it just the way it is.....beautiful, and a tack driver!
Appreciate all the assistance you gentlemen have provided.
John

Just asking, what gas cylinder lock screw do you have on your rifle?

Type 3 "HRA" marked.
