They're all the same except the early bikes had 19" front rim, and the RT2MX / DT2MX have the later conical hub.
DT250/360A also have the same wheels.
The good thing about telling the truth is that you don't have to remember what you said.

So are the full width pre 70 or can you use pre 75 conical hubs as a carry over
74 Yamaha YZ's - 75 Yamaha YZ's
74 Yamaha  flattracker's
70  Jawa 2 valve speedway's

For sale -  PRE 75 Yamaha MX stuff, frame, motors and parts also some YAM DT1,2,A and Suzi TS bikes and stuff

Interesting question, Freaky.

The conical hubs (322 prefix) weren't seen until the RT2MX of 1972 (I think it was '72 - definitely after 1970).

Logically, this means that they're NOT a legal part for pre-70 - however, I've wondered whether the eligibility allowance for 'All RT1 fitted with non-reed valve' means that you could front up with an RT2MX with an earlier barrel, and be good to go?

I've been running the full-width hub because there's no question about legality, they're cheaper and the brakes are great. And because I'm buggered if I can feel the weight difference.
