Thank you dayj1.... Yes, there are various forum locations that this exact question could have been posted. I am learning on line as I did every day when I opened my tool box to make a pay check. However, with this exact part is offered, I had research it and found the PDF lacking information...and so did the phone call I made to them. As with all things, if you are not learning something new, it's a boring day. If you're not researching (or asking), you bound to make mistakes. my wallet can't afford mistakes anymore. Thanks for pointing that out. I am new to forums, don't own a cell, and this build will be my last...for me, a simple daily driver 67 C10 longbed / w/wood!
