I have a 1959 ford 841 that I'm restoring. I'm currently rebuilding the steering that didn't work at all when I purchased it. My question is how many teeth should there be on each of the steering sectors gears? This tractor has 7 on the right sector and 11 on the left as your looking at it from the seat. All the replacement parts I've found have 5 on the right and 7 on the left. Any help would be greatly appreciated before I spend $300.00 on new sectors.
