All 2st Subframe help

Will a husqvarna sm 125 rear subframe from a 07 bike
fit my wr 250 04?
i destroyed my subframe on my wr 250 04. i got a frame from a 4st and was told it would fit. it didnt. it had to be modified in height and it is wider so my panels dont fit properly. i need to fit a new exhaust and that will need to be modified to so i hope i can find a sub frame to fit, and plastics and can

It should, but it may be missing side panel bolts holes. Those can be added with rivet type thread inserts.

thanks
another post said '06 and up has the same sub-frame for the WR250/300. 2000-04 will work but the end holding the back of the fender are shorter and don't support the new fender quite as well.''
are the 125s the same as the 250/300s?
are the sm the same as the cr wrs?

There are variations in them from 2000 to '06, but basically they will bolt to the main frame. I think '02 to present are very very close, but I'm not 100% sure of all the little details, but someone with a little savy will be able to work with it. I had a '02 CR250 subframe on my '07 WR250 and you couldn't tell any difference other than the shorter fender supports and I think SM are the same as WR.
