Re: '72 C-10 3-Speed to 4-Speed Swap?

No, same yolk as your 3spd. You might replace the front bearing before you run it(as a precaution), that is something I do whenever I have the gearbox out. I bet you will like the ratios, its a bit of a stretch from 3rd to 4th, but the rest get you rolling quick ,with a 3.42 or 3.73 gear......crazyL
