MR250 tank will fit right on, and I'm 99% sure a MT250 tank will fit. any CR250 tank from 73 to 76 will work.

Don't believe the 125 MT will thought.

The MR175 is a different tank than the 250, shorter.

But...

I've found that you can make other tanks from the 70's will work on cr/mr's, that big hole in the frame up by the sterring head allows you to run a long bolt through it. Not all tanks align with the stock threaded tank bosses, but many will align with the frame holes.

I found 2 big rubber 'corks' at a local hardware store that fit into the big holes, one per side. I drilled a hole off-center in the corks, which allow me to rotate the corks to adjust positioning. using this method, I mounted (among other experiments) a Clark RC125 tank. Loved the way it looked, but lousy range inthe woods.

I'll try to find a picture of what i'm trying to explain.
