Saurus cavalry not fitting together

I've just started putting together some saurus cavalry but the legs on the saddle do not even remotely resemble each other to the point that they don't fit together, is this a normal problem with the model and if so how would i go about fixing it? just as a note I have ordered some Drakespawn cavalry (dark elf cold ones) to replace the shoddy cold ones on the base model.

 

I don´t know what could be wrong. Maybe post some pics so we can see better?

 

There are 2 different molds, each only fits best with the correct second half.
and poorly with the other one. The two nest to each other on the sprue should be the right ones.

 

I niticed the two different types but neither fit, both leave gaps or don't line up correctly.
