DT rear axle to WR200 swingarm?

[YzDt85]

Hi guys. Does anyone know if there is a difference in length between the rear axle of the Dt125R and the WR200? I'm going to put a wr200 swingarm to the DT. I also need to know the lengths of the rear axle collars.

I found out that the shorter rear axle collar(part numper 90387-202U8) is the same on the Wr200 and Dt. If anyone has that longer collar(part numper 90387-206X8), could you measure its length? And if anyone has a wr200 rear axle, could you measure its length?
The rear axle part numbers of the Wr and Dt are almost the same
WR axle part numper 3XP-25381-00
DT axle part numper 3BN-25381-00
