You should buy my 3.55 gears for the 741. Cheap$$ Came out of my 67 slant six powered A100! They're good gears I have no use for. And then shop for a good used suregrip, and then check Amazon often for a rebuild kit. They have deep discounts out of the blue (like this one for a 489 case) and you might find a kit for approx $60+/- like I did. This kit is now $20 less than what I paid!! Ive seen deep discounts on 741 case components so keep looking over a period of time, sale will pop up. Just enter "chrysler 8.75" in the search box, scoll away!
