I was having a great deal of difficulty finding the Sprag rollers and springs. A very common part fifty years ago. After going to a dozen different site with little success I found by accident OPT. I could not find the part on their site either, but had a pop-up asking if I needed HELP. I typed a short message requesting information on rthis part, and was sent the next day the description and part number and telling me that it was in stock. I promptly ordered it and received it the next day with free shipping. I will remember this company when I need transmission parts. You should too..
