I change the gear box on my 83 k5 blazer.I switched it because I bought one that was already drilled and tapped. When I installed it nothing connected back up to it. The yoke and steering shaft dont fit because the shaft that connects to the yoke and steering shaft is thicker than the original one I had. I know I can replace the shaft w. the one I have from the OG box but would like to keep the thicker one because I have crossover steering w. a 6"lift and 37" tires. So therefore I assume a thixker shaft is better than the thin one I had previously. What can I do to make this work? What do I need to change? Let me know and thanks. HEre are some pitures.
