I just ordered the 81-166S and am curious what size screws I need for them. I wasn't able to salvage either screw due to age and rust!!

Hello,
The frame screw used with the 81-166S dual roller assembly would be our 33-104. Since you already have the rollers, you can go to your local hardware store and purchase two 1/4-20 X 3/4" stainless steel machine screws. Thanks for posting.
