Here is a link for anyone interested. I do not know the quality differences between Spin Rite and Tru Turn as I have never invested in a True Turn. I suspect TT may be better, but these have served me very well over the years. Virginia is very helpfull and shipping is very fast. If you used a propshaft other than 1/4 inch, you'll need an adaptor for the appropriate size. They have them as well.
