more than likely the part number brewski gave you is the correct one but there are 2 different motors that can go in this truck.
Look on the motor tag and verify the motor number.
For motor number 926000 (motor group number 923445) , it takes the number brewski suggests, 0916233 and uses spring kit 0916232.

For motor number 6R8550 (motor group number 989718) the parts manual suggests 0395369 brush kit and 0916232 spring kit.

Thanks a lot. I'll get that ordered right away.

Should be a part number 916233 for the brush set. This is for the drive motor.

Do you have the serial number?
