It looks like you are stuck with either buying used parts or having a custom replacement made.
There were a few guys posting parts over on scale4x4rc.org a few years back. Just search for Big Bear. It came up on a Google search also.
Good luck!
I finally got the axles turned down to upgrade to rear ball bearings, replaced the motor with one that fits in the plastic differential case, upgraded to an electronic speed controller, and a friend made me a front body mount. So it's all back together and works great. I'll post up pictures later.

Are you looking for a physical manual or will a scanned copy work?
I have a scanned manual available on the web page in my profile.
Or you can Google search "tokyo marui big bear manual" and my link should be first.

I have a Big Bear that needs 2 tires / but I prefer Tamiya products so either I restore or I sell...Chassis was cut for batteries, have hard shell body, rear end, bumper, etc......anyone?

The new cars running around just don't seem to match the durability of the older Tamiya's. I've driven the rims off my Boomerang, and have yet to break a thing! The shocks still hold oil! I recently rebuilt the front one, but only because I wanted a ligher weight oil. I also just got done installing bearings, and new tires. It handles like it's on rails!
The newer cars are built to tighter clearances, with less slack and slop, but they still are mere silouhettes of the cars ov yesteryears. Sure, the plastic has come a long way, and materials have grown stronger, but the balance between weight and strength has shifted. Now all the companies care about is building a car strong enough to make the mains. The old cars were meant to beat the ever loving crap out of, then install a fresh 1200 and go for it again!

I've recently bought a Big Bear that I will be fixing up but unfortunately there was no motor pinion included. It has the original 48 pitch gearing in the rear end. Could you tell me how many teeth the motor pinion should have? The manuals don't seem to state the tooth count anywhere...Thanks!

Let me know if you need more info or higher-resolution copies of these images.

I appreciate the reply! Unfortunately in looking at your album I can see that your gearbox has the upgraded 32 pitch gears (Strengthened Differential Gear Set). The original gears are a finer 48 pitch, and only have 2 bevel gears in the differential.
