help me with my rear belt please. pic request

[b2bomber]

this is my pic request! i did the rear axle shave. it was easy. now no matter what i do i can't get the stock belt or the o-ring to work. i've tried the motor just on top of the housing and i've tried with up to 4 spacers (the spacers i'm using are square's cut from where the atlas sticker was)under it. each time i would change belts to no luck. my request is tell me what belt/o ring your using. and give me a pic of it off the motor and being held up with a pen or screwdriver. so i know where i wanna try and be.
