DT1s aren't real flash as serious pre-75 racers, but anything is better than sitting on the sidelines talking about competing!
They're quite good (not brilliant) as pre-70 race bikes, but you need a square swingarm and a non-reed barrel to be pre-70 legal. Both these bits are relatively hard to find.

The one on EBay looks to have forks from a monoshock DT250/400 which are too long and not legal for pre75 (still got about the same travel though, so you might get away with it).
Seat bases are hard to get - if anyone is making re-pro ones, I'd be very interested myself.

Everything else is easy enough to deal with.

If you're looking at a low budget pre-75 racer, I'd look at a DT250A - they
are basically an MX250 with a lot more (easily removed) crap hanging off it. Parts are easier to find than DT1 stuff and they're a generation newer (albeit still quite closely related).
Plus the motors are very similar to the later YZ250/IT250s, so their better ratio gearsets and ignitions should fit.
The good thing about telling the truth is that you don't have to remember what you said.

Hilly. I have an RT1 remains. Dunno if its a 250 or 360. Engine if full of rubbish would need total rebuild. What you see is all I have. Any good to you?

Even allowing for the 19" wheel, I reckon not. It appears to sit high AND there's still about an inch of fork tube sticking out of the top triple clamp - I could understand wither one being an illusion, but not both.
The monoshock forks are about 30~40mm longer than the twin shock forks, which fits also.

An A is a 74 model.
The DT250B is almost the same and is allowed as a pre-75 bike with the right cylinder head - different shaped tank (doesn't matter) and different head (does matter, but you shouldn't have a drama finding an A item).
The good thing about telling the truth is that you don't have to remember what you said.
