Took me about 4 years to finally find a complete, bell housing, tranny & Hurst shifter, A-833 4 speed overdrive for my '72 C10. Logged 370 miles on my '72 truck to go get this thing a week ago. These things are hard to come across or have been for me to find. Now I just need to find a 67-72 C10 high-hump center floor piece & a cross member. Anyone else running one of these, should be a good addition for my driver. These are close enough to a 700R4 but you get the fun of the manual.
700R4 - 3.06/1.63/1.00/0.70
A833 O/D - 3.09/1.76/1.00/0.73
