Default Big Bear 350 Question?

I am repairing an older Big Bear 350 for a friend. I am not sure of the year as I have been unable to locate the Vin #. Frame is fairly rusted and I haven't seen it yet.

This machine was previously in 4wd all the time. No selector lever or button that has been attached while he has owned it. (he is the second owner) Front u-joints went out so he removed the front drive shaft to make it easier to steer.

What he would like to do is see if he can put a selector switch on it so the front differential can be shifted in and out of 4WD and reinstall the front shaft.

What I am looking for is if some one here can refer me to a parts diagram for a "missing part" OR tell me where I can find an aftermarket 4wd lock for the differential?

As far as I know this machine was made some time in the late to mid 90's.

I would also appreciate a hint on a VIN # location if any body has one?

Thanks in advance.

TLC, thankyou for the heads-up on the VIN #. There was a rusted spot there and I found it after I cleaned it up. I guesed the year correctly (1997) but now I know it is a YFM350FWB which helps me get parts.

I think the FW means its "full time 4 wheel drive".

KEvin R., thank you as well. Exactly what my friend was looking for. Just not sure he want to pay that much to get it. Do you know how that selector works?

Looks like some sort or plunger to move a gear? I may have to lookat it and see if I can machine up something similar on the lathe.

Thank you again gentlemen.
