I'm tired of 55mph out of my daily driver 75 GMC 1/2 ton. I want to install a saginaw code R10Q  overdrive tranny new style from 63-69. Alternatively, I would be interested in an A-833 new process tranny from 81-87 chev trucks it is a side winder four speed that I could convert to columm shift. If someone has one around and is interested in getting rid of it let me know, I'm in Saskatoon.
